This "Systematic knowledge and action, usually of industrial processes but applicable to any repeated activity" is how technology is defined. Technology simultaneously adds to and draws from a body of knowledge in which theory and practical experience are combined to provide tools and procedures for action. interact and compact in practise. Technology can be thought of as a definable, specific means of doing anything at its most basic level. In other words, a technology is a documented, transferable method of problem-solving. Technology has three stages of impact, according to Manfred Kochen. First, technology gives us the ability to do what we already do better, faster, and cheaper; second, it gives us the ability to do things that we are currently unable to do; and third, it alters our way of life. The field of information technology is new to explore.
Nowadays, Technology is advancing day by day. Most of the thing are done today with the help of technology. Technology makes the things automate and reduce human efforts. Technology plays a vital role in everyone’s life either in the form of comfort or security. To provide a input in enhancing the security, we are proposing a Human detection system. System is based on today’s most popular and growing IOT technology and PIR Sensor. System is operated through wireless network suing mobile phones. PIR sensor is used here to detect presence of human in nearby areas. System generates the alert if presence of human is detected. System ensures the security in restricted areas.
Clinical trials are crucial to the practise of evidence-based medicine and health care reform, as demonstrated by the recent federal funding focus on comparative effectiveness research. Clinical trials have an impact on society as a whole by raising the quality of healthcare offered, in addition to having an impact on the individual patient by creating a wider range of effective therapies. Clinical trials may, however, also expose participants to unforeseen hazards, and skewed knowledge drawn from problematic clinical studies may unintentionally damage patients. A well-designed clinical trial's execution may seem simple, but it is based on meticulous procedures and oversight that adhere to fundamental ethical norms. I give an overview of the moral principles in this project.
Dy substituted spinel ferrite nanoparticles of the composition Ni0.7Zn0.3DyxFe2-xO4 (x = 0.0, 0.015, 0.03) were fabricated by using sol-gel method. Structural and elastic properties of Ni-Zn ferrite were tailored by introducing the Dy3+ rare earth ions. Powder X-ray diffraction (XRD) and Infrared spectroscopy (IR) techniques were employed to investigate the phase purity, absorption bands, and elastic properties of the samples. The crystal structure and cell parameters were refined by using Rietveld refinement done by using Fulprof software. Rietveld refinement infers that the ceramics crystallized in single – phase cubic spinel structure having the space group Fd-3m. A slight increase in lattice parameter is observed due to substitution of Dy3+ ions in Ni-Zn crystal lattice. The vibrational study was achieved by using IR spectroscopy. Two major absorption bands (1 and 2) were observed in the frequency range of 350 to 800 cm-1 which confirms the co-existence of tetrahedral and octahedral sites of spinel structure. IR data was used to evaluate the elastic parameters like stiffness constant, young’s modulus, bulk modulus, rigidity modulus, poisons ratio, and Debye temperature. All the elastic moduli and Debye temperature are found increasing with increasing concentration of Dy3+ ions.

The crystal structure and lattice parameters of the Cu and Fe co-substituted disordered spinel series Cu0.7+x Cd0.3Zrx Fe2-2xO4 are investigated by means of X-ray diffraction (XRD) at room temperature(300K) and SEM results. The crystalline ferrite has been prepared by a modified Sol-Gel method. The analysis of XRD pattern suggests that the prepared Cu0.7+x Cd0.3Zrx Fe2-2xO4 (x = 0.1) spinel ferrite possesses single phase cubic spinel structure. The intense peaks of the XRD pattern were used to determine the average crystalline size. The crystalline size obtained from XRD data using Scherrer formula is of the order of ~0.5nm. So far no one has reported any crystalline size smaller than 0.5 nm. The calculations from SEM results agreed within the limits. In present work the lattice parameter, particle size, lattice strain and studied with the different concentrations (x = 0.1 to 0.4). The results were compared with ceramically prepared samples.

Today, and possibly for a long time in the near future, the complete driving task is too complex an activity to be fully formalized as a sensing-acting robotics system that can be explicitly solved using model-based and learning-based approaches in order to achieve fully unconstrained vehicle autonomy. This is especially true for unconstrained, real-time operations where the permissible range of error is extremely small and the number of limiting cases is extremely large. Until these problems are solved, human beings will remain an inevitable part of the driving task, monitoring the AI system as it performs anywhere from 0 to just under 100 percent of the driving. Overtaking and lane-changing is a critical part of vehicle automation. Though automation in automobiles has increased security and decreased environmental issues, it causes driver to be less active generating passive fatigue. This passive fatigue can lead to failure in responding quickly if needed. This led automation to keep driver active even though he/she is not required to take up full control all the time. This paper presents the need for alerting the driver during overtaking and lane-changing to avoid accidents and disastrous outcomes. The model uses image processing for lane detection and identification of obstacles, vehicles, and lane tracking. It calculates the relative velocity during overtaking and the system will share the scenarios with the driver, using alert systems. We demonstrate the capabilities and features of our system through real-world experiments using four vehicle’s videos processed on the road.

N-tert-butyl isocyanodichlorides is one of the important reagents in the synthesis of nitrogen containing acyclic and heterocyclic compounds. N-tert-butyl isocyanodichlorides undergo nucleophilic substitution reactions involving the displacement of both the chlorine atoms and can be potentially useful in the synthesis of various different 5, 6 and 7 membered acyclic and heterocyclic compounds. Synthetic chemistry of N-aryl and alkyl isocyanodichloride with special reference to their utility as intermediates in the synthesis of nitrogen containing 5- membered heterocyclic compounds is explored here. The condensation reaction of N-tert-butyl isocyanodichloride with different substituted N-aryl thiosemicarbazide resulted in the synthesis of various different substituted 1,3,4-thiadiazolidine.

The SRAM Semiconductor memory, utilize a bistable latch circuit to store logic 1 or 0 data. It differs from dynamic RAM (DRAM) which requires a periodic refresh operation to store logical data. SRAM power consumption varies with operating frequency, i.e., at higher frequencies, it consumes very high power, similar to DRAM. Because the cache included in the microprocessor required high-speed memory, SRAM can be used in the microprocessor for this purpose. DRAM is often used in processor main memory, where density is more important than speed. SRAM as well used in industrial, scientific electronics, and automotive subsystems. In this paper, the SRAM investigation report was studied to develop a new SRAM design for low power consumption.

In the deregulated power system, it would be difficult to assess and evaluate the prices for transmission lines in the power factor-based approach. In the Indian power sector, different electrical power users follow a regional price method of wheeling power rates. Because of the policy change, the postage stamp system is no longer suitable for the Indian electricity generation. It is because nonlinear power flow is very influential in creating prices between transmission lines. The MW-mile method is used for real power wheeling price assessment, and MVA-mile method is employed for the accurate and reactive power wheeling price assessment. For various flow-based processes to be efficient, decision-makers should consider the different optimization techniques. This paper proposes a new method by which wheeling prices can be allocated for the Indian utility IEEE 14-bus system using the MVA-mile and MW-mile method based on the PSO algorithm approach for optimum power flow calculation In this paper, MW-Mile based, MVA-Mile based incremental cost of power demand addition and power factor-based approach are utilised. Sensitivity analysis will take place. It is also pertinent to study the DC load flow based costs.

Seismic analysis of structural systems with floor diaphragms has been a requisite in the recent past. The duty of a structural engineer is to be prudent about the behaviour of every structural system adopted. Amongst the structural systems that are adopted world over, diaphragm with rigid and semi-rigid floor plate are adopted widely in the analysis. This research focuses on the backstay effect i.e. podium structural interaction with the tower area and consideration of retaining wall as increment of lateral stiffness as specified in latest tall building code IS6700:2016 for low and high rise structures. In the current study models were prepared with low to high rise storeys with rigid and semi rigid diaphragms considering backstay diaphragm placing tower at centre and corner. The models were subjected to seismic forces; response spectrum along with the combination of the gravity loads. The structural responses like natural periods, base shear, displacement and inter storey drift were also studied.
In a multi-functional tall building, generally the building has a more extensive plan area and higher lateral resistance at the lower story level than the above story levels. So, the scope of this study is to understand the realistic behaviour of such structures under lateral loads considering the backstay effect as per IS: 16700(2017). The present work focus on the effect of podium structure of single tower structure connected by a common podium at the interface level under seismic load. For this purpose, the simulation model with varying tower height and podium height is created in the ETABs and it is analysed for the equivalent static and response spectrum method. In this study, the effect on the top displacement of the tower connected with podium structure under equivalent static and response spectrum method of analysis is observed. The backstay forces that are developed to resist the lateral overturning actions at the interface when the lateral horizontal forces are transferred from the tower to the podium are studied. The unfavourable effect of podium on the shear force distribution at and above the interface level of the structural wall is observed. The positioning of the tower on the podium structure is found to be the reason for the differential displacement between the structural walls.
The primary objective of this research is to investigate the behaviour of tall concrete buildings featuring structural walls combined with Special Moment Resisting Frames (SMRF) when subjected to seismic loads, as defined by the IS 1893:2016 and IS 16700:2017 codes. To achieve this, a comprehensive seismic analysis was conducted using the Linear Dynamic Response Spectrum Method in ETABS 2020 software.
Energy sources are of two types renewable and non-renewable. ‘Renewable’ resources are those that recover their capacity in a time significant by human needs. Examples are sun light or wind power, when natural phenomenon that are the primary source of energy are going and not depleted by human demands. Now days, sometimes we complete our demand of electricity with the help of solar energy. This is done with the help of solar panels. By maintaining the solar panel always perpendicular to the incident sun rays we can receive maximum amount of energy. For this purpose, we have to set the tracker below the solar panel which always sets the panel orientation towards maximum intensity.
This paper introduces 17th and 18th century distemper decorative paintings in Indian, and it discusses the painting technique and the painting materials used. Distemper decorative paintings from these periods are found in many countries, but seem to be less valued than oil based decorative paintings. The object of this paper is to raise awareness of the importance of these paintings and the fact that what we are looking at today differs from what the artist originally painted. The distemper paintings in Mugal periods Building as life Red fort, Taj Mahal India Gate etc. illustrate the importance of understanding altered paintings. A disappeared blue colour was detected in some of the decorative components in the wall paintings. This is believed to originally have been a green colour which would totally change the appearance of the paintings in Mugal period buildings
