The development of information and communication technology at this time has touched all sides of life. Almost no side of human life is not touched by this information technology, which is more synonymous with the world of computerization. No exception also with the computerization that is popular in the corporate environment and government agencies. If in ancient times everything was still done manually. However, at this time all leaders and management have realized the importance of this information technology products that can facilitate them in carrying out the day-to-day corporate functions. Decision Making System of goods purchasing is one of the determinants of the accumulation of goods. If the decision is taken right then stockpiling of goods can be avoided. In this thesis the authors designed a web-based system that helps Management in making the decision of the purchase amount of goods. the system was developed by using Microsoft Visual Studio 2010 and using SQL Server database processing applications. The end result of system design is expected to help minimize the accumulation of goods.

In present, more and more attention has been put on the effort of protection of personal data and also new encryption technologies are derived. In this article, we introduce a personal information protection technology, global unique identifier (GUID), which is developed by National Institutes of Health U.S. and used for personal health information protection. The GUID is an identifier that allows researchers to associate and share data specific to a study participant without using or exposing personally identifiable information (PII). The GUID is made up of random alphanumeric characters and is not directly generated from PII/Protected Health Information (PHI). It has been approved by the NIH/USA office General Counsel for secure sharing of anonymized database. In our study, we used GUID as key identifier for health data collection from aboriginal tribe in a health promotion project. © Springer Science+Business Media Dordrecht 2015.

Recently, due to the deceleration of the markets in developed economies, the growing demand for infrastructure development in emerging countries has become more important in the global economy. Conventionally, developed countries have improved their infrastructure from government's and supplier's viewpoints. However, this approach has not always been the best when working in emerging countries. In this study, we propose an innovative approach inspired by the concept of social innovation, centered around the social viewpoint. It consists of a system for the successful implementation and sustainable development of new infrastructure projects in emerging countries. We focus on an ongoing railway project in Vietnam by looking at the applicability of this concept there. Finally, the concept is evaluated through rounds of discussion with experts from the government, academia and industry. It was concluded that the project is perceived to have great potential for the region, and it is regarded with high esteem by all stakeholders.

Context. The recurrent nova RS Ophiuchi (RS Oph) underwent a thermonuclear eruption in August 2021. In this event, RS Oph was detected by the High Energy Stereoscopic System (H.E.S.S.), the Major Atmospheric Gamma Imaging Cherenkov (MAGIC), and the first Large-Sized Telescope (LST-1) of the future Cherenkov Telescope Array Observatory (CTAO) at very-high gamma-ray energies above 100 GeV. This means that novae are a new class of very-high-energy (VHE) gamma-ray emitters. Aims. We report the analysis of the RS Oph observations with LST-1. We constrain the particle population that causes the observed emission in hadronic and leptonic scenarios. Additionally, we study the prospects of detecting further novae using LST-1 and the upcoming LST array of CTAO-North. Methods. We conducted target-of-opportunity observations with LST-1 from the first day of this nova event. The data were analysed in the framework of cta-lstchain and Gammapy, the official CTAO-LST reconstruction and analysis packages. One-zone hadronic and leptonic models were considered to model the gamma-ray emission of RS Oph using the spectral information from Fermi-LAT and LST-1, together with public data from the MAGIC and H.E.S.S. telescopes. Results. RS Oph was detected at 6.6σ with LST-1 in the first 6.35 hours of observations following the eruption. The hadronic scenario is preferred over the leptonic scenario considering a proton energy spectrum with a power-law model with an exponential cutoff whose position increases from (0.26 ± 0.08) TeV on day 1 up to (1.6 ± 0.6) TeV on day 4 after the eruption. The deep sensitivity and low energy threshold of the LST-1/LST array will allow us to detect faint novae and increase their discovery rate. © 2025, CC BY.

We construct a SCUBA-2 450-μm map in the COSMOS field that covers an area of 300 arcmin2 and reaches a 1δ noise level of 0.65 mJy in the deepest region. We extract 256 sources detected at 450 μm with signal-to-noise ratio > 4.0 and analyze the physical properties of their multi-wavelength counterparts. We find that most of the sources are at z . 3, with a median of z = 1.79+0.03-0.15. About 35+32-25% of our sources are classified as starburst galaxies based on their total star-formation rates (SFRs) and stellar masses (Mo). By fitting the far-infrared spectral energy distributions, we find that our 450-μm-selected sample has a wide range of dust temperatures (20K . Td . 60 K), with a median of Td = 38.3+0.4-0.9 K. We do not find a redshift evolution in dust temperature for sources with LIR > 1012 Lfi at z 1012 Lfi population to the SFR density rises dramatically from z = 0 to 2 (/(1 + z)3.91.1) and dominates the total SFR density at z and 2.

In this paper, we have proposed Single Inductor Dual Output (SIDO) buck-buck and boost-boost DC-DC converter using improved RC ripple regulator control. The proposed SIDO buck-buck converter has the characteristics of lowripple and high control frequency. RC ripple regulator control can not be applied to SIDO boost-boost converter because RC ripple regulator undergoes self-excited oscillation and two self-excited oscillating controllers make the SIDO converter unstable. Thus we proposed the priority circuit for RC ripple regulator control. The proposed control circuit improves response characteristic and simplicity of the control circuit. Simulations are performed to verify the validity of the proposed SIDO converter. Simulation results indicate good performance of the proposed SIDO converter. © 2016 The Institute of Electrical Engineers of Japan.

In this paper, EMI reduction method for switching power supply circuit by using PLL circuit as reference signal whose spectrum is spreaded, is proposed. M-sequence pseudo random signal is employed for PLL spectrum spread. Next, we extend this low bit M-sequence pseudo random signal to spectrum spread signal called "pseudo analog signal." The proposed pseudo analog signal can realize that the effect of the spectrum spread is wide even if the number of bit of the pseudo random circuit is small. Simulations and measurement are performed to verify the validity of the proposed method. Simulation and measurement results indicate that the proposed method have a large effect of the spectrum spread. © 2016 The Institute of Electrical Engineers of Japan.

This paper presents experimental data and analyses from the oscillation frequency of CMOS ring oscillators (ROs). The measurements are analyzed in order to separate the coefficient of variation (CV = σ/μ) behavior of both within-die (WID) process variations and Die-to-Die (D2D) process variations. Three different RO's sizes distributed over a total of 96 ROs per chip were measured in 32 different chip samples, all from a single MOSIS Multi-Project-wafer in a commercial 65nm CMOS process. All ROs were measured with varying power supply voltages, from nominal VDD (1.2V) down to nearthreshold (0.45V), resulting in a sample space of 18.432 points of interest. Statistical analysis results are shown regarding each RO stage size, the applied power supply and the correlation of both to the WID and D2D variations. The increase on D2D and WID coefficients of variations at the near-threshold supplies is very significant, as explained by increased delay variability at the moderate inversion regime of the FETs. The 96 test ROs occupy a total area of 200 x 480 μm2 in each test chip. © 2015 IEEE.

This work describes a procedure for evaluating the mismatch between MOSFET transistors in a test array and connected as stacked-pairs. The transistor mismatch is characterized by measuring the gate voltage dependence of the DC voltage established at the middle node of the common-gate MOSFET stacked-pair. This procedure is modeled as the onresistance ratio of these two transistors and it is performed by two simple measurements. Various pieces of information on the MOSFET mismatch characteristics (e.g., channel length variation and threshold voltage variation) can be extracted. The test structure was manufactured in 180nm CMOS technology, and the test array was designed to allow a large number of MOSFET stacked-pairs, from transistors placed in different parts of the layout to vary gradually the distance of the paired FETs. © 2015 IEEE.
