The objective of this paper is to find the optimum combination on different machining characteristics during electrical discharge machining process of Al-12%SiC Metal matrix composite. Central composite design (CCD) method is used to investigate the effect of three process parameters such as peak current (Ip), pulse on time (Ton), flushing pressure (Fp) on the four response parameters like Mate...

This paper proposes the design of a weighted-rotor energy harvester (WREH) in which the oscillation is caused by the periodic change of the tangential component of gravity, to harvest kinetic energy from a rotating wheel. When a WREH is designed with a suitable characteristic length, the rotor’s natural frequency changes according to the wheel rotation speed and the rotor oscillates at a wide a...

Introduction There is limited data available in the use of soft casting to offload heel ulceration. Heel pressure ulceration is a costly problem in the health board involved in this study with 15% of in-patients having heel pressure ulceration (HPU).This has led to heel ulcers coming under the 1000 lives campaign in Wales. Soft cast is a quick, cost effective treatment modality for foot ulcerat...

Thirteen school children aged 12.21 ± 0.98 years carried backpack and one-strap athletic bag during their stair ascent and descent. The load weights of the bags included 0%, 10%, 15%, and 20% of body weight. A Novel Pedar System was used to record and analyze the insole pressure during stair descending with different loads. The first peak force was 1.59 times the second peak force. A load of 15...

In Swedish forestry, final felling is usually done by a harvester and a forwarder. These machines are heavy and the risk for rutting and soil compaction can be considerable under unfavourable soil conditions. The aim of this study was to evaluate effects of forwarder tyre inflation pressure on rutting and soil compaction after final felling. Three levels of forwarder tyre pressure were studied,...

− A new controlled-clearance pressure balance has been developed to improve the hydraulic pressure standard for pressures up to 1 GPa. For several controlledclearance piston-cylinders, characterization experiments based on the Heydemann-Welch model were performed to estimate the effective area of them. The results for the piston-cylinders of different pressure ranges are exemplified in this pap...

Driver errors such as careless and aggressive driving behaviors are one of the key factors contributing to road traffic accidents. It is, therefore, essential that drivers are aware of their actions when they are in control of the wheel responsible for not only their own lives but also passengers and bystanders on the road. Driver monitoring and advanced driver assistance systems have already b...

Tumor blood flow (TBF) plays a fundamental role in tumor growth and treatment, and is characterized by spatial and temporal heterogeneities. Here we show that the interstitial fluid pressure (IFP), which is higher in tumoral tissue than in normal tissue, coupled with the tumor microvascular pressure (MVP) and the higher permeability of tumoral vessels, can explain the sustained oscillatory beha...

Event based sampling occurs when the time instants are measured everytime the amplitude passes certain pre-defined levels. This is in contrast with classical signal processing where the amplitude is measured at regular time intervals. The signal processing problem is to separate the signal component from noise in both amplitude and time domains. Event based sampling occurs in a variety of appli...

The photodegradation behavior of a straight asphalt was investigated using a new method “photodegradation test of asphalt binder using pressed thin film samples”. Although the photodegradation caused by outdoor exposure is limited to the near surface, the results confirmed that the degree of degradation during 1 to 2 months is more severe than that by the pressure aging vessel (PAV) test, which...
