This paper investigates an improved stator flux linkage observer for sensorless permanent magnet synchronous motor (PMSM) drives using a voltage-based flux linkage model and an adaptive sliding mode variable structure. We propose a new observer design that employs an improved sliding mode reaching law to achieve better estimation accuracy. The design includes two models and two adaptive estimat...
Biota in managed forest landscapes may be at risk from habitat fragmentation that prevents dispersal among subpopulations. Management provisions to provide connectivity are often considered independently for aquatic and terrestrial species. Of increasing concern is that dichotomous approaches are economically inefficient and may fragment populations that rely on both water and land. To provide ...
Objective: To compare the corneal stromal demarcation line depth after Epithelium-On and Epithelium-Off crosslinking in patients with keratoconus using anterior segment Optical Coherence Tomography (AS-OCT).
 Study design: Quasi-experimental study.
 Place Duration of Study: Armed Forces Institute Ophthalmology, Rawalpindi Pakistan from Jun 2018 to 2019.
 Methodology: This study i...
The design preciseness, the material used in productivity plus the time are coming the most important factors in motor manufacturing. Consequently, the use of interior permanent magnet synchronous machines (IPM) in hybrid vehicle seemed to be the best demands. However, and due to the earth magnet materials increasing prices such as Dysprosium and Neodymium, automobile manufacturers have looked ...
A large number of independent and interacting factors affect seating comfort such as seat shape, stability, lumbar support and seat height. Although many subjective comfort studies have been conducted, few of them considered seating comfort from its subassembly level. This paper analyzed the automotive seat cushion designed with geared four-bar linkage for the seat height adjustment. The operat...
There is a strong paradigm shift in the literature recently, on how rural development and urban development affect one another. The conventional wisdom of the last three decades suggests that urban and rural developments are separate and compete with each other for resources. However, a closer looks reveals that this is far from the truth. Relationship and range between urban-rural have many va...
BACKGROUND Timely linkage to care after HIV diagnosis is crucial as delayed access can result in poor patient outcomes. The aim of this systematic review was to synthesise the evidence to achieve a better understanding of what proportion of patients are linked to care and what factors impact linkage. METHODS Systematic searches were run in six databases up to the end of February 2017. The gre...
Genome-wide variance components linkage analysis was performed on 4 latent factors underlying metabolic syndrome derived from 10 risk factors. The latent factors represent obesity and insulin, blood pressure, lipids and insulin, and central obesity. The metabolic syndrome factor scores were derived in 4 ethnic groups recruited in 3 Networks of the Family Blood Pressure Program: GENOA (blacks, H...
BACKGROUND New molecular technologies allow high throughput genotyping for QTL mapping with dense genetic maps. Therefore, the interest of linkage analysis models against linkage disequilibrium could be questioned. As these two strategies are very sensitive to marker density, experimental design structures, linkage disequilibrium extent and QTL effect, we propose to investigate these parameters...
