Questions related to Routing
I observed an assembly process of a ferromagnetic nanoparticles into a 3D cubic microstructure in aqueous media at 120°C. However the assembly process didn't involve any solvent evaporation or external magnetic force. Can anyone recommend or suggest the route for this formation?
when we do synthesis of nanoparticle through Green route, we always notice the initial color change by adding Plant Extract and the Salt like Zinc acetate in ZnO NPs etc. and if the color change occur we say our NPs synthesized. so what's the logic behind this, why the color change occurred.
How is fuzzy logic specifically applied in the trusted routing protocol, and what advantages does it offer over traditional routing methods ?
Concerning my PhD project, I'm curious about the placement of electronic toll stations within a city, particularly in Europe. I'm interested in whether they are typically situated sequentially along one or more routes, arranged in a grid network, or perhaps organized in a circular pattern.
I am also wondering if all electronic toll stations in a city are typically connected to each other through the available links among them, or is there any possibility that two or more toll stations are not connected (in a city)?
Thank you in advance for your help.
What are the key challenges and threats associated with routing in dynamic and potentially untrusted vehicular environments, and how can fuzzy-based protocols address these challenges?
What are the importance of energy in an ecosystem and its routes of uses and important feature of energy flow in the ecosystem?
I am working on a VANET simulation with NetSim and aim to introduce a clustering mechanism similar to the one used in IoT/WSN setups. The objective is for each vehicle cluster to establish communication with a certain Road Side Unit (RSU). Is it feasible to achieve this through MATLAB-NetSim co-simulation?
I'm working on a routing and scheduling problem in the home care services context. I consider a break as a dummy patient, so routing and scheduling are also implemented for the break node (with some conditions). For some reason, I need to determine whether a visit occurs before or after a break. I defined two binary variables "Zikt" which means if patient i is visited by doctor k on shift t before the break, and "Z'ikt" for after the break. I added 2 new constraints as follows:
S(b,k,t)-S(i,k,t) =l= M* Z(i,k,t)
Z(i,k,t) + Z'(i,k,t) =l= sum((j), X(i,j,k,t))
P.s: S(b,k,t) is the starting time of break by doctor k on shift t
S(i,k,t) is the starting time of visiting patient i by doctor k on shift t
X(i,j,k,t) is if doctor k on shift t goes from node i to node j (binary variable)
In the first constraint, if the left-hand side becomes positive, Z(i,k,t) will be 1.
The second one is guaranteeing that Z and Z' could get value if patient i was visited by doctor k on shift t.
By adding these 2 constraints to my model, the result of my S variables get wrong.
I think it's better to rewrite the first constraint so that it becomes related somehow to X(i,j,k,t), but I can not figure out how to do it.
I'd appreciate it if anyone could help me.
In articles that present different synthesis routes of Cu doped ZnO nanoparticles via sol-gel, they use a temperature of 60°C for this. So far I have not found any justification for most authors to use this temperature. Could anyone help me with this issue?
I want to perform QST2 or QST3 using gaussian 16 to determine the transition state. I have got several saddle points for reaction with single imaginary frequency. I am trying to get IRC trajectory starting with TS-geometry.
Should I go to run QST2 or QST3 after getting IRC path?. Or QST2 OR QST3 are necessary apart from TS-Berny to classify the transition state. Is the rout line of QST2 input is same as for TS?
I am trying to run a calculation using the HF/LANL2DZ level of theory, and am interested in visualizing the canonical orbitals and the basis functions. The molecule of interest is pentagonal planar (D5h point group), and I would like to choose the coordinate system such that the py basis functions on the terminal atoms are pointing towards the center of the molecule.
Does g09 support this? What keywords would I have to add to the route section to achieve this?
Thank you very much!
I am working on an HMS model and each time I go to run the model I get a warning code for my first two reaches and then the model shuts down. Specifically, it says "WARNING 41169 Muskingum routing is unstable with the given parameters for reach-X." Is there any place where I can look up the warning codes or an easy solution to fixing my routing issues? Thank you

I need to inject tamoxifen into mice at P12 and P14. I would collect retinal tissue at P30. Does anybody have any suggestions for the dose and the route of administration for this age?
Any suggestions would be of huge help! Thank you!
I am trying to model a three-lane approach roundabout in VISSIM. I have assigned static vehicle routing decisions for each approach lane. However, there is a queue forming at the location where the dual carriageway link ends, and the approach roads begin. E.g., A vehicle turning left at the roundabout will make a sudden left turn from the approach right lanes near the roundabout to enter the leftmost approach lane which is causing serious queues in the right lanes of the roundabout. Can anyone advise how to solve this issue?
I am planning to administer chemotherapeutic drugs to nude mice via the oral gavage route. What is the optimal pH range for the solution that can be given via oral gavage?
Pheromone Table : This table is organized in a manner similar to the routing tables in Distance-Vector Algorithms but it's input τij is a Probabilities, not distances, and they indicate to the extent appropriate choice for each node of the adjacent nodes to be as a next node when route to a particular destination in the network.
I assigned a static route to the eastbound (right) direction with a specific flow (I have tried different values as well), but no vehicles are passing through that route! I added two data collection measurement points as shown in the picture to check the count, and it always reads zero vehicles. Any ideas about this issue?

Public transport routes and timetables in citys are determined through a collaborative effort between local transport authorities and public transport companies. Local authorities are responsible for identifying transportation needs in the community and working with transport companies to establish adequate routes and schedules.
When determining routes, factors such as population density, existing infrastructure, and access to key locations such as schools, hospitals, and business centers are considered. Public transport companies may also conduct surveys and collect data to determine the most efficient routes and schedules. Once routes are established, timetables are developed based on factors such as expected demand, frequency of service, and local regulations. Timetables are subject to change due to factors such as construction, traffic, and changes in demand.
How exactly is this process organized in your country (city)? What are the laws governing this process? Maybe there are review articles on the subject?
I am working on the control of urban traffic networks. I have the urban traffic volume data that consist of attribute like location, route length, number of vehicles per day, ADT, ADTT and so on. How can I determine trip production or trip completion flow using historical data? The network is a large regional network i.e heterogeneous network, that requires partitioning into homogeneous subregions, the second question is how can I partition the urban traffic networks?

In my city, passengers are transported by buses. The number of routes is very large. Many routes overlap. As a result, the costs of public transport from the city budget are high. The task is to reduce such costs by optimizing the route network. For me, any detailed information about methods for optimizing the route network of public transport is relevant. Where can you find such information?

The problem that I am working on is that there are 10 salesmen , 50 routes and each route travelled distance.
Now I have to allocate the routes among these 10 salesman so that overall distance covered by each salesman is almost comparable.
Basically it is a unbalanced assignment problem with multiple jobs allocation, can some one help me with query with some documentation and if possible if there is any python code/library for this.
I would like to continue my research on underwater sensor network routing protocols.

Kindly suggest on the following issue.
I am trying to sinter Al 6061 powder compacted sample prepared through PM route.
I have the following parameter during furnace sintering :
Stage 1: O to 350 @ 5 C/min
Stage 2: at 350 C for 30 min
Stage 3: again heating to 630 C @ 10/min
stage 4 : at 630 kept it for 5 hours
Stage 5: cooling to room temp.
I have taken the photo graph of the sintered sample after crushing and the same attached with message. So I am very doubtful about its sintered quality. It is not looking like casted Al6061after braking into fragments. I found still some powder particles are loosely bonded .
Kindly share your thoughts and experiences with your valuable advices and suggestions to be followed for getting better sintered sample .
What is the till best known etching route for etching V4AlC3. Is there any optimized parameters in case of etching with HF acid.
I am working with a simulation of an aircraft traversing a route where the position of the aircraft and waypoints are in the form [X, Y, Z] where X and Y are the 2D Cartesian coordinates on a flat plane and Z is the altitude from that flat plane.
However, we are now implementing routes in the real world with waypoints in the form of [Lat, Lon, alt]. What are some valid ways of converting these coordinates to a Cartesian counterpart and have them exist on a flat plane?
These routes are never more than 50 miles in one direction so I dont need to convert the entire global coordinate system, just at most 50 miles worth. Additionally, I am aware that there are ways that convert to a Cartesian coordinate system for lat/lon but they always result in a [X, Y, Z] coordinate, assuming a point on a sphere in 3D space.
Human activities have greatly changed the natural environment since the Industrial Revolution. Have migratory birds changed their migration routes? Why can migratory birds do this?
In two dimensional borophene we usually discuss phases, structural and theoretical evolution of borophene.
1. But how can we differentiate the structural instability and scalability of borophene?
2. What is mean by Green Borophene ? Is this any specific kind or synthesis route ?
3. What is stable form of borophene ?
Can any one here suggest me the suitable articles related to these question or can give his/her opinion.
Hello All. I know how to calculate energy fluence (W/cm^2) of a pulsed laser, but if I shift the laser beam at a certain speed (cm/s) along a route I guess energy fluence will decrese. How scanning speed affects the energy fluence into a fixed point, is there a formula available? Thank you!

In India the LSD is spreading rapidly. It's not possible through mechanical transmission only.
If we need to provide some external storage of some kind to nodes (since they do not store anything in memory in a non storing mode of operation) in a RPL network, how can we do that? I need the nodes to have access to some kind of data during the downward routing in a non-storing mode of operation.
There are 2 cluster formation strategies:
1. Distributed stretegy
2. Centralised strategy
which one is best suited for routing in internet of vehicles?
My model has 2 sequences and 14 stations. Each sequence uses all 14 stations but the "flight time" from one station to another differs. I have thought about using an attribute or a variable but am having a difficult time developing my model. Any help would be appreciated.
The simulated peak in HEC HMS model is one day after the observed peak.
The method which i am using:
1. Muskingum method for routing
2. SCS curve number for loss
3. SCS unit hydrograph for Transform method
4. Constant monthly method for Baseflow
I have done changes in certain parameters just to match the peak time so, the NSE is 0.857 but percent bias is 50%.
As i am unable to figure out how to reduce this 50% percent bias.
2nd question is:
What will be the perfect duration for validation w.r.t calibration in general.
I tried the Buchwald -Hartwig amination of pyridyl 2-amino pyrimidine with 4-iodopyrazole using various Pd catalysts and Xanthphos. The iodo compound is fully consumed in the reaction. An extra spot is formed in tlc at the end of the solvent front. But after doing the column no product is formed. NMR shows no characteristic peaks. Where is the iodocompound goin? Can anybody suggest a possible synthetic route?
I’m planning to conduct a traffic count in the coming days for selected route near my university in Budapest. Currently, I'm attempting to identify the rush hour time along the route. Accordingly, I'm trying to use an approach based on real time information other than the traditional method. Underneath, please see the steps I took so far and kindly share your helpful thoughts:-
- I checked the tomtom previous rush hours profiles (2021, 2020 and 2019) for Budapest, which suggests the overall city rush hour to occur on Monday between 7:00 to 8:00A.M.; however, this may not be the reality in the particular route I’m considering in 2022. Therefore, I checked the Traffic Stats function of the TomTom Portal, which offers very limited dates in 2021 for the trial version and information on the speed profile couldn’t help in identifying the rush hour in the route. Therefore, please kindly share your thoughts in identifying the rush hour a selected route?
- Aside from the traditional approach, if you can suggest any other reliable method on the subject, that would be greatly appreciated.
Thanks in advance!
I'm curious to learn about resources (i.e., standard practices) regarding the creation of a survey instrument and/or analysis of micro-mobility travel mode decisions and travel behaviors (route preferences) in a university environment? Thanks and I look forward to any and all comments!
I read a thesis which used the formula v = K(S^0.5) to determine the flow velocity in a channel. The value for conveyance K was adopted from Ward and Trimble (2004) and was mentioned to be equal to 5 for a river bed composed mainly of sand and gravel. Can anybody help me find the K value for a river bed which mostly consists of boulders with patches of vegetation?
I have used the following parameters to simulate:
1. Loss method: SCS-CN, 2. Transform method: Clark UH, 3. Routing: Lag.
My simulated peak occurs 1 day after the observed peak.
It shows "Warning: Time of concentration increased to one time interval at subbasin X" which I'm assuming is the reason for the discrepancy.
What parameters can I adjust to shift the peak by 1 days and to esolve this error?
I need help to come up with a possible topic proposal related to any existing problems can be in community, Hospitals, Banks which can be solved using multiple Operations Research topic. Thanks.
I am trying to use HEC-HMS for streamflow modelling of a river. The thing is that I have only one gauge in my study area located at the outlet of the catchment. I've been through some materials which mention that inflow data is a basic requirement. However, the gauge flow data at the data at the outlet has to be considered as outflow data if I'm not wrong. Is there any other way to go about this?
I wonder how realistic and practical are the routing attacks in RPL such as Blackhole, Sinkhole, Greyhole, Sybil etc. These attacks have been studied and solutions have been offered. But is there any known case where these attacks have actually been carried out in reality? Internet of Things devices are not like traditional computers where there are manned by a person, how can someone takes possession of such IoT devices and implement the RPL routing attacks?
I want to model a system in AnyLogic comprised of 10 machines. Jobs (my agents) are created and can do any sequence of machines, i.e., random routes. For instance, jobs can do:
machine1 -> machine7 -> machine2 -> exit
machine9 -> machine2 -> exit
So, once they exit a machine, jobs can go to any other machine.
I have modeled my machines as services, so I have 10 services. My doubt is how can I implement these random routes/sequences of services? I.e., once a job finishes a service, how can it randomly select the next one? I am aware that one option is to use multiple SelectOutput at the end of each service, but is there another way to model this?
Hello everyone, I’m now working on my thesis about work-family/life interface.
I got some statistical issues that Ive nearly heard it before, so I’m here to raise the question and hope someone could give the suggestion.
I’ve got and 2 mediators which mediate X-Y by dual routes. Besides, there are 2 moderators which moderator1(w) possibly would moderate x-m1 & x-m2 at first stage, the others(z) would moderate m1-y & m2-y. Forming the model is called moderated mediation.
moderator1(w) is a moderator which is assessing by 2 concepts, and I looked up the literature by Kreiner(2006) suggested that it could use latent congruence model by SEM approach. And others recommended response surface regression by polynomial regression.
By reading articles, I have no idea how to use these methods to fit in my moderated mediation model. Does anyone have met such questions?
the x somehow could have the curvilinear effect on Y which totally mediated by m1 & m2. Is it even possible put x quadratic into latent congruence model or response surface regression into analysis the moderated mediation model?
Induction at gestation day 7 led to abortion and loss of pregnant mice. My suspicion is that my route of exposure intraperitoneal at 5mg/Kg was too high and this has been used previously by other studies in literature.
I'm working on to read data from Vissim. I've a network created, it was initially showing vehicles movement during simulation but now it's not showing. I can see VehicleNetworkPerformance results captured for few of the links, few of them are 0. This network has different routing setup for different links.
I want to see the vehicles moving in the UI. What could be the issue?
