Joint Estimation of CSI and IQ Imbalance, and Compensation of IQ Imbalance in Spatialy Multiplexed MIMO-OFDM Receivers
Abstract: This study presents a novel method for estimating Channel State Information (CSI) and IQ imbalance and compensating IQ imbalance in a spatially multiplexed MIMO OFDM receiver. Our approach integrates estimation of IQ imbalance with CSI estimation using an OFDM training frame, thus eliminating the need for additional pilot symbols for IQ imbalance estimation. This technique streamlines the process and avoids extra overhead. We conducted simulations on a 2×2 spatially multiplexed …

A Review of Locking Protocols for Concurrency Control in Parallel Databases
Abstract: In modern database systems, many transactions may run at the same time. When several users try to access the same data or update the data simultaneously, then it creates a problem such as inconsistency data, lost updates or misinformation and may lead to conflicts between the transactions and deadlocks. To avoid these types of issues and maintain the correctness of the database, concurrency control protocols are mainly used. This paper …

Stakeholder’s Influence on Design-Construction Planning
Abstract: The design phase requires several interactions between the client and the architect as compared to other phases. Major decisions on the project were finalized during this design phase with the inadequate involvement of the forthcoming stakeholders—fabricators, contractors and vendors. Further, fragmentation in design and construction phase had led to redesign and rework during the construction execution. Additionally, this fragmentation had design solutions that had not involved constructability issues, which resulted …

Clinical Trials: A Brief Review
Abstract: Clinical trials, according to the World Health Organization, are used to test new medicinal entities on humans after they have been studied in animals. Clinical studies are usually divided into five stages. Clinical pharmacologists study phase I pharmacokinetics, safety, and gross effects on human volunteers. If the drug passes the test, it moves on to phase II testing, where pharmacokinetics, safety, and therapeutic efficiency are studied on a small number …

A Pseudo Randomly Triggered Integer Cycle Control (PRT-ICC) for AC Loads to Reduce THD, EMI and RFI
Abstract: Several proportional voltage control techniques exist for AC loads. The most popular of these are phase control (PC), cycle control (CC) (including integral cycle control (ICC) and fractional cycle control (FCC)) and pulse-width modulation (PWM)). Phase control utilizes triggering for loads away from zero voltage or zero current and generates odd harmonics with amplitudes higher than ICC and PWM. Integral cycle control, causes more harmonics (both even and odd) overall …
