Smart Parking System using Cloud based Computation and Raspberry Pi

Abstract: The internet of things plays a vital role in interconnection and automation of various physical devices, vehicles, home appliances and other things. With the help of software, various sensors, actuators, these objects connect and exchange data. This automation of devices enhances a person’s standard of life and way of living, which is a need of future. A similar need is discussed in this paper. In this project a smart parking feature is discussed which enables a user of find a parking location and a free slot in that parking space inside a city. This project focuses on reducing time wasted on finding parking space nearby and on going through the filled parking slots. This in turn reduces the fuel consumption and standard of living.

Cathodoluminescence versus dynamical epitaxy of Ba-ion irradiated α-quartz

Abstract: Doping α-quartz with photoactive ions without destroying its crystalline structure appears to be a promising way to tune its luminescent and structural properties. We have achieved dynamic solid phase epitaxial regrowth and cathodoluminescence of 175keV Ba-ion irradiated α-quartz in the temperature range from 300 to 1170K. Rutherford Backscattering Channeling analysis showed that the amorphous layer produced by 1×1015 Baions∕cm2 at 300K had almost disappeared at an implantation temperature of 1123K. Room temperature cathodoluminescence exhibited dramatic changes in the optical spectra as a function of the implantation temperature and allowed to distinguish between color centers related to quartz, ion-irradiated silica and implanted Ba. Between 770 and 1100K, room-temperature cathodoluminescence showed a predominant blue and other weak bands connected to various known defects in the Si-O-Si network. However, after achieving almost complete solid phase epitaxial recovery, only a violet band at 3.4eV remai...

Role of Ligand–Ligand Interactions in the Stabilization of Thin Layers of Tin Bromide Perovskite: An Ab Initio Study of the Atomic and Electronic Structure, and Optical Properties

Abstract: We report results of the state-of-the-art ab initio calculations on two-dimensional (2D) hybrid halide perovskites capped with surface ligands to understand their effects on the stability with respect to bulk MASnBr3 (MA = CH3NH3). Considering the thinnest (one-unit-cell thick) layers R2SnBr4 with surface ligands of different lengths (R = MA, ethyl ammonium (EA), butyl ammonium (BA), and phenylethyl ammonium (PEA)), it is found that van der Waals (vdW) interactions between the long chain molecules play a crucial role in enhancing the stability of the layers. The vdW contribution in ligand–ligand interactions increases with increasing length of the ligands, and interestingly, the stability of BA2SnBr4 and PEA2SnBr4 layers becomes better than bulk MASnBr3 and comparable to that of inorganic bulk CsSnBr3. Furthermore, our calculations on the 2D-3D BA2SnBr4 system in which the surface ligands connect the neighboring perovskite layers suggest further enhancement in the stability of the layers. The present stud...

Transcriptome analysis predicts mode of action of benzimidazole molecules against Staphylococcus aureus UAMS-1

Abstract: Antimicrobial drug resistance is one of the most critical problems that plagued the human race in modern times. Discovery of novel antibiotics is important to counter this threat. Accordingly, herein we have reported the discovery of substituted benzimidazole class of molecules with antimicrobial property (specifically against Staphylococcus aureus). They were initially identified through a random screening and a novel catalytic synthetic strategy was utilized to access them. in vitro screening and phenotypic profiling revealed the antimicrobial nature. De novo transcriptome and gene analyses predicted the putative targets. This work provides a solid foundation for developing the benzimidazoles as a target specific antimicrobial preclinical candidate.

Fiscal policy in an emerging market business cycle model

Abstract: Emerging market economy business cycles are typically characterized by high consumption and output volatility, strongly counter-cyclical current accounts, and counter-cyclical real interest rates. Evidence from the wider EME and less developed economy business cycle experience suggests however that real interest rates can also be pro-cyclical. We reconcile the pro-cyclicality of real interest rates with the above facts by embedding fiscal policy into a standard emerging market business cycle model. We show that fiscal policy makes real interest rates a-cyclical or pro-cyclical. We use the model to replicate some of the key features of the Indian business cycle.
