In this study, the adhesion of ice to solid substrates with different surface properties is compared. Clear ice, similar to atmospheric in-flight icing encounters, is accreted on the different substrates under controlled conditions. The ice adhesion behavior is investigated by means of a dynamic vibration testing technique with an electromagnetic shaker initiating ice de-bonding in the interfac...

A review of the Giardia duodenalis sequences currently available on the GenBank database was completed to compare the different genotyping loci (small subunit ribosomal DNA, glutamate dehydrogenase, triose-phosphate isomerase and beta giardin) for their ability to discern assemblage and subassemblage groups and infer phylogenetic relationships. In total, 405 Giardia duodenalis sequences were so...

OBJECTIVES Tissue processing for years is carried out by the conventional method, which is a time-consuming technique resulting in 1-day delay in diagnosis. However, in this area of modernization and managed care, rapid diagnosis is increasingly desirable to fulfill the needs of clinicians. The objective of the present study was to compare and determine the positive impact on turnaround times o...

The aid process is challenging from an allocation standpoint because donors must choose between many organizations with imperfect information about all of them. This paper explores a possible method for correcting the information asymmetry inherent in allocations through comparative impact assessments. The approach combines methods from impact studies and process evaluations to create a framewo...

the objective of this study is to measure the city of tehran’s environmental quality in 2006 (the last census year). primarily, with a comparative analysis of a variety of urban sustainability indicator models, a collection of 54 indicators have been chosen and categorized as indicators of increase or decrease in urban environmental quality in the form of a simple mathematical model. based o...

This paper performs a comparative evaluation of two QoS architectures, RSVP Reservation Aggregation and Scalable ReservationBased QoS, aimed at providing QoS levels similar to the ones provided by the well-known RSVP/IntServ architecture, but scalable enough for use in high traffic core networks. The comparative analysis, based on each model’s characteristics and on simulation results, shows th...

Feature Based Modelling has demonstrated the ability to produce agent models with high accuracy in predicting an agent's future actions. There are a number of respects in which this modelling technique is novel. However, there has been no previous analysis of which aspects of the approach are responsible for its performance. One distinctive feature of the approach is a purpose built induction m...

UNLABELLED POLITICAL BACKGROUND: As a German novelty, the Institute for Quality and Efficiency in Health Care (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen; IGWiG) was established in 2004 to, among other tasks, evaluate the benefit of pharmaceuticals. In this context it is of importance that patented pharmaceuticals are only excluded from the reference pricing system if they...

Established approaches to design and evaluate usable systems are challenged by systems for wearable, handheld, or mobile devices. There are extensive methods and guidelines that describe how the usability of stationary computer systems should be evaluated [4,6]. This is complemented with experimental evaluations of the relative strengths and weaknesses of different techniques [1,3]. However, in...

Segmentation of brain tumor manually consumes more time and it is a challenging task. This paper detects the tumor inside the brain by doing segmentation and extraction of the tumor which is been detected. To prove the efficiency of the detection of brain tumor we have performed a comparative study of two segmentation algorithms namely “watershed segmentation algorithm” and “k-means clustering ...
