What are the differences between shop drawings and builder works drawings, and what are the differences between them?
As their name clearly states; shop drawings are drawings produced by the shop; ie. as an example when a client buys an equipment for installation the shop produces drawings; called shop drawings; for the subcontractor to implement.
Builder works drawings; as their name implements also; are drawings produced by the builder or subcontractor who is responsible for executing works. Builders use builder work drawings on site.
The shop drawings; produced and used by the by contractor engineers based on design drawings; details are based on standard specifications and tender requirements. On the other hand builder works drawings are produced by the subcontractor based on shop drawings, and used by his engineers and builders, builder works drawings are based on the details of equipment the subcontractor is planning to install; and must with shop drawings details.
The consultant compares shop drawings with approved design drawings, and work on site with shop drawings for final approval.
Relevant answer
Answer
A builder work drawings will provide in detail the component representation and client communication of what the engineer designed. Contrarily, shop drawings is for fabricators and technician use only and it is basically for determining how components will be produced and placed during the construction process.

Design , as an object, as a practice and as a knowledge, is an integral part of the society thus cannot be ignored when studying power and oppression in society. the objective of this study is to critically look at ‘design’ as a social phenomenon and study power and oppression in design by paying attention to the networks and relationships between the domains of design practice, production and everyday life.

Answer
In the US, over and over we witness the needs of people with low incomes, diverse cultural ideas and the wrong color skin routinely deprived of basic human services and educational opportunities. I’d like to suggest that design as a way of thinking (vs making objects) can be part of changing this. But we’ve studied this, created awareness and used grants to fund small endeavors to bring change.
More often we fail. We fail because our ideas have little to do with things people want and their values.

Hi
Does anyone have experience in designing multi-story wastewater treatment plants?
In fact, I want to reduce wastewater treatment footprint because we have a problem in terms of land.
Relevant answer
Answer
I could tell you many "stories" about wastewater treatment plants (WWTP's) but I guess that mean "storey" (multi-level). As a matter a fact we designed one about 30 years ago in South-Korea where the footprint was so small that we installed a 3-level/storey WWTP including a stack of 2 final clarifiers (one on top of the other). Many more levels could be added as needed. This is a matter of proper hydraulic design (gravity flow and pumped flow) combined with efficient construction design (civil & structural works).

Question

In my current project, I want to answer if various cognition items (ratio, 30+ of them, may get reduced based on a separate factor analysis) predict moral outrage - in other words, do increases in item 1 (then item 2, item 3, etc) predict increases in outrage in a significant way. Normally, this would be a simple regression. But then I complicated my design, and I'm having a hard time wrapping my head around my potential analyses and whether it will actually answer my stated question, or if I'm over-thinking things.
Currently, I'm considering a set-up where participants will see a random selection of 3 vignettes (out of 5 options) and answer the cognition items and moral outrage about each. This complicates matters because 1) there is now a repeated measure component that may (or may not?) need to be accounted for and 2)I'm not sure how my analyses would work if the vignette selection is random (thus, all vignettes will show up the same number of times, but in different combinations to different people). I am anticipating that different vignettes will not be equal in their level of DV (which is on purpose - I want to see if these patterns are general, not just at very high or very low levels of outrage).
When originally designing this, I had wanted to average the 3 vignette scores together for each subject, treating them as single, averaged item values to use in a multiple regression. But I've been advised by a couple people that this isn't an option, because the variance between the vignettes needs to be accounted for (and the vignettes can't be shown to be equivalent, and thus can't be collapsed down in analysis).
One potential analysis to combat this is a nested, vignette-within-individual multilevel design, where I see if the pattern of cognition items to outrage is consistent between vignettes (level 1) and across subjects (level 2), to account for/examine any vignette-by-cognition/MO pattern interactions. And this makes sense, as MLMs can be used to compare patterns, rather than single scores.
But I can't wrap my head around what part of this set-up/the output I would look at to actually answer my question: generally, which, if any, of these cognition items predicts outrage (regardless of vignette, or across many scenarios)? And can this approach work when the vignettes combinations differ between subjects?
Or is this the incorrect analysis approach and another, simpler one would be more fitting? For example, is the averaging approach workable in another format? What if all vignettes were done by all subjects (more arduous on the subjects, but possible if the strength of the analysis/results would be compromised/overly-complicated)?
Confirmation that my current analysis approach will indeed work, help with what part of the output would answer my actual RQ, or suggestions for an alternative approach, would be appreciated.

Hi I want to know more about how are new cities implementing biophilic design to their buildings and how much this is growing. Also how important is the LEED certificate becoming for this implementation.
Relevant answer
Answer
Hi dear Santiago.
Real architecture is called architecture in which human thoughts and feelings are taken into account and this architecture creates a perfect fit that pays attention to structure and function at the same time. We know that our relationship with nature promotes health and well-being, and this relationship can also improve physical function. People who live in a building do not just need to work, play, eat or sleep. They want to be inspired and inspired by their surroundings, to feel comfortable and strong in it. They need a space that makes them more comfortable. The solution to architectural sustainability is to work in harmony with nature. That is, one must understand nature, explore it with sensitivity, and at the same time avoid damaging nature's systems. The architect-planner should pay attention to the concept of biophilia, which causes the continuity of performance and health and emotional states of residents and individuals and leads to positive reactions in the environment, and the general process in the architectural predominance to such things as:
1- Making natural and physical frameworks friendlier
2- Optimal organization of energy consumption
3- Ensuring the effective relationship between human progress and optimal management of natural resources in reducing the negative effects of climate change.

Answer
There are various types of pollution, so each one or combination may take a specific survey or inventory, and assessment. Some of the various types may include solid waste, sanitary waste (human, animals, pets, etc.), industrial wastes, air pollutants, water pollutants, soil pollutants, etc. Coming up with a working proposal would probably necessitate involvement of leaders, community, landowners, and others interested, such as industry, hospitality such as hotels, citizens, etc. Leaders might include political representatives, health, religious, agencies, police or enforcement, various technical pollution experts, etc. Funding to develop comprehensive plans, improvements and management as well as monitoring may be another important area to address. Plans or programs might be developed to help address specific types of pollution, or circumstances, and some of these might be voluntary citizen responsibilities, and some might be legalized or regulated, and funded by taxation, communities, industries, or government actions.

Hi all, I'm looking for any studies using Co-Design, Participatory Design, or Design Thinking specifically in developing countries. Of specific interest are technology-based projects and the uptake of technology in developing countries especially rural regions.
If you have come across any, or were involved in any, please let me know Many thanks in advance P.J.
Relevant answer
Dear PJ White,
Participatory design (originally co-operative design, now often co-design) is an approach to design attempting to actively involve all stakeholders (e.g. employees, partners, customers, citizens, end users) in the design process to help ensure the result meets their needs and is usable.
Benefits of Participatory Design in Web Development
The most attractive benefit of the participatory design is bringing a fresh, unique set of eyes into the design process. Developers and engineers work daily to create web designs and interface models, but do not share the same perspectives of end-users
Co-design, design with users, not for them. Participatory design you design for users and get their input.
A human-centered, systems-minded, and strategy-aligned design approach for social sector leaders. ... Strategic planning is logical and ensures that an organization's activities actually lead to its intended outcome, rather than busy work. Human centered design is action-oriented, deeply human, and experimental
The design thinking process is broken up into five specific design thinking stages: empathy, definition, ideation, prototyping, and testing.

First drone development dates back to 1917. Why just about a century later this technology starts booming?
Does it has do to with the related enabling technologies?
Relevant answer
Answer
In my opinion, despite the fact that the history of drone development dates back to 1917, it was only at the beginning of the 21st century, i.e. one hundred years later, that the technology and applications of drones developed, which is related to the ongoing technological progress in various supporting technologies in the field of batteries that store electricity, plastics materials, ICT information technologies in remote control applications, etc. Besides, it is only in recent years that the development of drone applications has occurred. In 2020, the SARS-CoV-2 (Covid-19) coronavirus pandemic also caused an increase in the use of drones. Currently (December 2020), in the context of the pandemic, drones are used to transport medicines for sick people, drugs and food to places with poorly developed road communication, blood plasma of people who have recovered from Covid-19 disease, etc. In the future, drones will find many more applications as equipment for courier companies delivering different products to individuals. Moreover, conceptual technological solutions for the construction of flying cars, which are also drones, are currently being created. Transport flying machines are also built, which with their shape and avionics technology were created as a combination of the concept of a helicopter with a drone. This type of progress in the field of avionics would not be possible without, for example, constantly improved and more efficient batteries that store electricity, more and more perfect electric motors and devices that charge said batteries with electricity. Perhaps in the future, as part of the ongoing technological progress, the growing demand for electricity, the growing demand for drones and the growing importance of environmentally friendly energy sources, drones will be produced powered by photovoltaic panels, which will cover the drones.

hi hope you are well in this current climate,
I am doing a project on Catia where i need to design a scissor jack like the one attached. however i wanted to know how i can calculate the dimensions and angles the criteria i have been given is it needs to hold 1.5 ton and have a minimum 30mm lifting capability
Relevant answer
Answer
Let's see. Breaking this down into its separate components, start with the simplest.
The maximum delta lift distance, from max down to max lifted, is going to be 2L. At its lowest point, the distance from the floor to the vehicle would consist of only the height of the stand and that top block.
The maximum Fs, which would be the maximum tension experienced by the long screw which lifts and lowers the jack, would be F*sin(α). As the jack goes from full down to full up, that weight goes from being entirely held up by the screw (sin(90) = 1) to being entirely held up by those four L components (sin(0) = 0).
And as you might therefore conclude, at max lifted position, F1 = F2 = F3 = F4 = 0.5*F. That's because when fully lifted, the weight is held up equally by F1 and F3, on the left, and by F2 and F4, on the right, while at the same time, at that fully elevated position, the long screw holds up none of the weight.

I have just completed my PhD thesis - Adapting Photovoice to Visualise and Influence Environmental Behaviour across Australia, Bangladesh, and China (Monash University - Design), exploring using photovoice methods across multiple geographic sites to facilitate dialog between and amongst these communities using various participatory techniques, specifically with innovation in audience engagement.
The journey has taken me across 17 discrete participatory-action-research cycles
spanning 4 years, where I partnered with 19 local organisations to run 80 workshops, 8 community exhibitions, and 3 community interview events across 4 separate sites spanning Australia, Bangladesh, and China. Over 700 participants attended workshops and collectively created over 500 photo-stories. I focussed on environmental behaviour, but these methods - like photovoice generally - are applicable to a wide range of themes.
Now I have finally emerged from the tunnel of my PhD, I am looking for future opportunities to use these learnings in other projects and connect with like-minded peers.
Thus I am interested to see who else / what other current and future projects are working on similar methodological adaptations in photovoice or related visual methods?

Greetings,
Recently I have been assigned several tasks of making presentations for webinar by a superior. The presentations are mainly about treatments in oncology such as immunotherapy and targeted therapy.
In the process of making the presentation, a few graphs such as kaplan-meier survival are needed to be included in the PowerPoint presentation. However, I then suddenly remembered that several speakers in symposiums had this sort of beautiful graph (Picture 1.). When I check the PowerPoint file, it is as if they design or make the graph in the PowerPoint directly, resulting in a well-suited graph for viewing.
On the other hand, the best that I could do was downloading the figure or slides directly from the journal and even then, it was still horrendous occasionally and unsuitable for presentation in my opinion (Picture 2.)
I want to ask whether there is an easy way to make beautiful graph like in picture 1 without allocating significant time. I also want to know how they do it. Do they use professional designers in the firstplace or is there an automatic software to make this?
Many thanks for the help

Hi,
We conducted an experiment analyzed by multiple regression. We measured each participants' personality with HEXACO model and their accuracy in the task. Our predictors are the six dimensions of HEXACO and criterion variable was their accuracy.
So what is the design of this experiment? Is this a repeated measures design?
Relevant answer
Answer
You may analyze it as a repeated records model, in which each of the six dimensions are explanatory variables. Then, you need to model your residuals to accommodate the fact that the same participant was evaluated across all six dimensions. An equivalent model would be fitting the random effect of participant instead of modeling the residuals - they will result in the same model.
One question is: how does your response variable look like? Is it categorical, proportion, or continuous quantitative? This will impact the type of statistical method to be used. For example, if it is ordered categorical, you need to use an ordered multinomial (logistic, probit, etc) regression. If it is proportion, then you may use Poisson/Negative Binomial. If it is continuous quantitative, then a simple linear model would be enough.
Please let me know if this is what you were looking for. THanks, Nick

Suppose I have a 100 Farad, 2.7 V supercapacitor which has a dimension of length = 45 mm and Diameter = 22 mm. I want to understand-how these length and diameter values were fixed and if any design equation is guiding it?
Relevant answer
Answer
The capacity of a supercapacitor can be measured in (F / g) or (F / cm2) or (F / cm3)
The working voltage = 2.7, indicates the maximum voltage to which the SC can be charged.
Using the equation:
Cs = I. t / m (Vf-Vi)
Cs = I. t / A (Vf-Vi)
Cs = I t / V (Vf-Vi)
Where i = is the discharge current
Where Vf-Vi = is the work potential
Where m = is the mass of the active material
Where A = is your area
Where V = is the volume, this can be found with the data: 45 mm and diameter = 22 mm.

Background
We have an RNA-seq project on small intestine. The experimental design were like this: Four physiological states, each with three individuals (biological replicates), each individual with two samples (two parts of small intestine), thus 4 physiological states × three individuals × two parts. The reason we included two parts of same individual’s small intestines is that we want to take consideration of tissue heterogeneity, by pre-analysis of these replicates the difference between two parts is actually not significant.
Question
Here is my question, when I applied a generalized linear model for the differential expression analysis on samples from two physiological states (e.g. DESeq2), should I treat samples as independent one thus 6 vs 6, or merge two samples from same individuals thus 3 vs 3. For the later one, can I regard it as technical replicate and merge reads from the two part together, or merge counts calculated from the two parts (e.g. collapseReplicates function in DESeq2). Or, should I include "individuals" as a blocking factor in the differential expression analysis.
There is an intensive discussion about biological replicates and technical replicates, like these https://www.biostars.org/p/54380/
but I am still confused about my situation, should I treat the two tissue parts from same individuals as biological or technical replicates.
Two parts of small intestine from same individuals, It's technical or biological replicates?
Relevant answer
Answer
Thanks Pro. Pan
It is a ticklish question to distinguish between technical and biological replicate in our situation, thank you for your time and your answer. The work the question from have been peer-reviewed and published (see details below). I’d like to share our answers. Firstly, we tried to answer two question, one is whether the variation between the two replicate is from biological factors (e.g. sex, age, or tissue heterogeneity), or from technical factors (e.g. sequencing lanes, library generation). It is reasonable that the two parts of small intestine were not biological replicates, just as you said, two samples were from the same individual and they shared same genetic background, then the variation between the replicates were from sequencing or other technical factors. However, as our original intention is inducing the variation from tissue heterogeneity, although they come from close part of small intestine, it’s not precise to just regard them as technical replicates and merge them in downstream analysis. The other question we want to answer is, how to take consideration of tissue heterogeneity but also avoid pseudoreplication caused by the same origian of the replicates. In our work, we randomly assign the two samples from the same individual to “PartA” and “PartB” and incorporate the blocking design into differential expression tools with ~sampled part + physiological states. By fitting design model above, we can compare the four physiological states with adjustment of the baseline differences from tissue heterogeneity (see details in )

Unused engine oil flows through the shell side and cold water in the tube side. The internal diameter is 15mm with a wall thickness of 2mm. I want to know if wall thickness and conductivity should be ignored in the calculation of the heat exchange area. I've tried out the calculation both ways, by first assuming that these factors are ignored and then by taking them into consideration and I noticed a significant difference between the two cases hence I am unable to decipher if it is wise to ignore the wall thickness and conductivity. I am aware that in most cases, with thin walled tubes, wall thickness and conductivity is ignored. Is it advisable to follow that approach of most cases?

What do you think respected architecture researchers?
Thank you.
Relevant answer
Answer
We can explore the importance of sketching in the design process through three provinces:
1- Its function as a thinking tool during exploration, abstraction and developmental phases.
2- Its function as a communication tool, the value of sketches as an external storage medium for ideas and as an unspoken language between the architect and himself, between the architect and the design team and between the architect and the general public
3- Its function as a tool for analysis and description, the worth of sketching in exposing the architect thoughts, since sketches are a device used for both the architect and the observer to explain both the product's substance and the design process used to approach the object.
For more discussion on the important of the sketching into the conceptual phase in architecture you can see the interesting work of: Suwa, M., Tversky, B

Developing a Rating System for Building Energy Efficiency Based on In Situ Measurement in China
By: Zhao, L (Zhao, Li) ; Zhou, ZN (Zhou, Zhengnan)
DOI: 10.3390/su9020208
Abstract
Building energy consumption in China recently surpassed the US building consumption, and it is expected to increase significantly in the next decade pushed by the continuous population and urbanization increase. In response to that situation, the Chinese government introduced a series of building energy codes and rating systems to assess and enhance the building energy performance. The purpose of this study is to develop a rating system for the building energy efficiency, based on in situ measurement. The system is intended for office buildings in China's cold zone. An evaluation framework, graphic dominant point, and principle of data collection and processing are illustrated in this paper. Three existing buildings were rated under the new rating system. The authors believe that the new system will contribute to a more accurate and comprehensive understanding for asset holders and occupants, that report on the extent to which energy efficiency buildings have been reached. Rating results are expected to be a reference for the retrofitting of existing buildings and the design of new buildings. In addition, the outlook for the rating system was also discussed.

The roof will be pitched and the model will need to illustrate attachment of photovoltaic panels and rainwater re-direction. The structure is designed to securely contain 3-4 machines about the size of 10 gallon paint buckets; the enclosure of which will require some basic moving parts i.e. hinges.
Material possibilities: Extruded and/or corrugated sheet steel, aluminum, wood, concrete, mud/thatch.

With the more recent studies on the impact of blue light from screen for sleeping, it seems there is a physiological response that does not match this design rule.
Is there a difference in wavelength, or is there a cutoff of exposure from when it is calming to when it becomes a response to stay awake? Or am I misunderstanding something in the two cases?

I am trying get results from the hfss after design information an antenna and wanted to find if my impedance is matched or not.at 50om .so how can I do that....thanks in advance
Relevant answer
Answer
Be aware that HFSS DOE NOT display input impedance. It displays the feed-line(2D model, aka PORT) impedance, which is NOT influenced by the model solution. 2D ports are simulated separately in order to determine excitation fields.
But, you can ESTIMATE input impedance using Z, or S parameters, knowing port characteristic impedance, which is Zo().
Now, for antenna there is no second port, so input impedance is ALMOST Z(1,1), which you can plot on the chart. You don't even need to know Zo(1). But the 3D-simulated section of the feeding line introduce its loss, and phase shift, so you should use DEEMBEDDING option in the port configuration dialog, which also accepts parametric data. But it is just a multiplication by 4-component S-matrix of a transmission line. So do NOT make deembedding distance longer than the said feeding section.

Complex products such as aircraft, trains and ships are high-value, long-life assets that are typically managed as a fleet over a period of 20 to 30 years.
Managing technology upgrades (modifications/ engineering changes) can be challenging because of the complex relationships and interdependencies that exist between different systems components.
An additional factor relates to the phenomenon of design divergence that can be observed as a

Dear Morris,
Hello
The question which has been inquired by you is, in fact, an important and also interesting question in field of “Design for Changeability” in discipline of systems engineering.
Dear , it is important to note that your concerned question actually encompasses a lot of sub-questions including design for “Adaptability”, “flexibility”, “reconfigurability”, “reliability/robustness”, and so forth. In addition, “propagation of change into the system due to change of one or more component(s) of the system under study. Moreover, in this regard, quantitative measurement of change in the system is another interesting and relevant issue.
As a useful suggestion to address and deal with the above challenges in system design, you could have a comprehensive study in both Axiomatic Design (AD) theory (especially, the information axiom of this theory to compute information content of a design to satisfy the system requirements) and “Design Structure Matrix (DSM) (especially, for the aim of studying the role of dependencies and/or interaction between any interest pair of system elements).
I think that the article attached to this reply could be a useful step to begin.
Hope the above helps!
Good luck!

A correct interpretation of reliability analysis is determinative for researchers and industrial developers to refine their design and also prepare proper maintenance scheduling and safety analysis. However, I still see that many designers prefer to use classical safety factors instead of reliability analysis techniques. what's your sense about this.
For example, imagine that you are going to buy a bearing and I say you this bearing's reliability is 94% for the expected life of 5 years. it means that if you test 100 bearings under normal performance, almost 6 of them should fail after 5 years. does this analysis makes sense for you in your research and development?
and if the answer is yes, how do you use the outcome of reliability analysis in your research area. the answer is important for me because I am going to start developing commercial software for reliability analysis and it is important to see what are the expectations of experts from the reliability analysis methods.

Hi! My name is Ana and I am a student who is studying biophilic design, I was wondering what is your opinion regarding biophilic design and LEED certificate, do you think it has a future, do you support it, advantages and disadavantages? Thank you! Have a great day
Relevant answer
Answer
You should clarify your question. What do you mean by 'does it have a future'? Biophilic design is currently a term with broad meaning. A problem with such terms is that they could be interpreted widely. Everyone can read it differently. One thing that is obvious is biophilic design is very much context- and case-sensitive. One strategy or technique that may function properly in a specific project in a specific climate or site may terribly fail in another project, site, climate or time. It is a key to take into account deeply various layers and factors of local and global sustainability when prescribing a solution for a particular case. Green isn't necessarily sustainable. Search more on the difference between green and sustainable. These are fundamentals. Then you could extend principles and connect with standards and regulations such as LEED. That is a secondary issue.

Relevant answer
Answer
Hello Milad,
The Conjoint Analysis template in Question Pro uses a rating scale (7="Definitely will buy", 6="Probably will buy", etc.) in response to a set of options that are made up of combinations of your four design attributes. With four attributes, each at two levels (yes/no, high/low, etc) then you have 16 profiles in a full-factorial, which would be reduced to eight profiles in a main-effects-only fractional-factorial design. So each of your respondents gave you 8 ratings for your different profiles. Something like this from each person:
  • a b c d Rating
  • -1 -1 -1 -1 4
  • 1 -1 -1 1 5
  • -1 1 -1 1 3
  • 1 1 -1 -1 7
  • -1 -1 1 1 4
  • 1 -1 1 -1 6
  • -1 1 1 -1 2
  • 1 1 1 1 1
Is that correct?
You already have a regression model here. Conjoint Analysis, of the type you have used, is simply multiple regression applied to experimental design data. (The main difference is the jargon - it kept a lot of overpaid consultants happily occupied throughout the 1980's and 1990's)
Rating is your Dependent Variable, and your four attributes are the Independent Variables.
  • If you run the regression at the level of the individual person, then you have a total 8 degrees of freedom total, and five df for regression, leaving only 3 df for error. In this case, you'd ignore the significance figures for the regressors (attributes) and use Adjusted R2 for goodness of fit. From my experience, I throw out any respondents who have individual-level Adjusted R2 less than 0.70.
  • Alternatively, you can run your regression with all respondents together - this assumes that each respondent is a random variation around a group-level utility function. Unless your respondents are very similar to each other with respect to crowdsourcing preferences, expect rather low regression coefficients.
  • Alternatively, you can run a cluster analysis on the rating scales for all of your respondents and find groups of respondents (market segments) who have similar patterns of preferences for crowdsourcing, and then run group-level regression models for each cluster.
