It plays an important role for quality of manufactured product. For assembly of product drilling, boring, reaming process are used. Many input drilling parameters are feed rate, spindle speed, drill diameter, cutting fluid, depth of cut, work piece material, tool material, helix angle, point angle, clearance angle, types of tool, etc. The performance parameters for drilling are Material removal rate, surface roughness, thrust force, torque, tool life, etc. This paper illustrates a literature review on effect of drilling drilling process parameters such as feed rate, drill diameter, spindle speed on thrust force. The thrust force is calculated by the force sensor or dynamo meter. In this paper it studied that the feed rate and spindle speed are the significant factor for thrust force.

Such distribution systems, including medium and low voltage networks, face difficulties regarding fault detection and localization as compared with high voltage transmission systems. High impedance fault (HIF) resulting from an open (or broken) conductor in medium voltage (MV) overhead lines represents the most challenging problem in such an environment. The aim of this paper is to report on a new method to detect and locate such high impedance faults generated by downed conductors. These faults usually produce very low fault currents that are usually not detectable by the feeder conventional over-current protection schemes. The proposed Open Conductor Detection (OCD) system is based on distributed voltage measurements performed at low voltage (LV) sides of distribution transformers throughout the distribution network with GSM network communication to locate the faulty line se...

Methodology: This randomized study was conducted at Department of Surgery, Hayatabad Medical Complex, Peshawar, from April 2017 to April 2019 and included 110 patients using consecutive non probability sampling technique. Typhoid ileal perforation was diagnosed on the basis of history, physical examination and investigations like leukocytosis, positive typhidot and pneumoperitoneum on X ray erect abdomen. The patients were divided into two groups using lottery method. Group A underwent primary repair and Group B underwent ileostomy. The procedures were performed by highly experienced surgeons. Patients were followed at 2 weeks, 1 month and 3 months after surgery. Data were analyzed using SPSS version 22. Hospital stay in both groups was compared using independent t-test and post-operative complications were compared using Ch...

A 25 years old lady, 34 weeks primigravida was referred from the Emergency Department to the Medical Unit Khyber Teaching Hospital-MTI, Peshawar with four weeks of fever, progressive jaundice, pruritus, night sweats and weight loss. LFTs showed cholestatic picture, ERCP showed scanty intrahepatic giving beading and autumn tree appearance typical of sclerosing cholangitis. CBD was normal. Doppler U/S of hepatic and portal vein reported normal. She was started on steroids, ursodeoxycholic acid and antibiotics 3rd generation cephalosporins to which she did not respond well. This prompted a Liver biopsy which showed Hodgkin's disease having mixed cellularity. She was shifted to specialized oncology unit for further management where she died of irreversible liver damage. This is a rare case of secondary sclerosing cholangitis in Hodgkin's lymphoma of liver and the first case reported to our Hospital.

The strength of RBAC is considered due to the incorporation of concept of roles. Separation of Duty (SOD) is a constraint that implements least privilege principle in RBAC. Dynamic Separation of Duty (DSD) is a powerful constraint to control internal security threats. Current RBAC standard implements DSD on the level of roles. This creates various problems.

The Global Navigation Satellite System (GNSS) enables such navigation by providing precise timing, velocity and positioning information to any adequately equipped receiver world-wide. A core capability of these receivers is to identify all visible satellites from a snapshot of received signal. This identification process, called signal acquisition, must be performed in shortest possible time in practical solutions. Conventionally search for the desired satellite in a serial fashion which involves large number of computations. Recently Fourier transform based methods were proposed to speed up the processing. However such a solution requires complex domain signal processing. We propose a partial-code serial search algorithm that significantly reduces the computational time with same reliability of acquisition results.

Received Signal Strength based positioning provides economical viability to enabling these applications. Although extensive research has been carried out in this area still tedious implementation and lengthy de- velopment life cycle prohibit wide scale adoption of this technology. We present a new approach based on Fuzzy ArtTMap neural network that signiflcantly reduces development time. Besides shortening development time of location systems this approach shows competitive accuracy and allows dynamic expansion of location aware site.
