Copositivity plays an important role in combinatorial and quadratic optimization since setting up a linear optimization problem over the copositive cone leads to exact reformulations of combinatorial and quadratic programming problems. A copositive programming problem may be approached checking copositivity of several matrices built with different values of the variable and the solution is the ...

abstract background: in recent years, there has been a rise in the number of premature births. mothers of these newborns experience a high degree of stress over time. since a more comprehensive understanding of this phenomenon can help the healthcare teams in detecting the deficiencies and needs of such newborns’ mothers for a better and more effective intervention, the present study was carrie...

Balanced acceptance sampling is a relatively new sampling scheme that has potential to improve the efficiency of spatial studies. There are two drawbacks of the design, it can have low entropy and some of the unbiased estimates can not be calculated. In this paper, such shortcomings have been addressed by integrating simple random sampling with balanced acceptance sampling. In a simulation stud...

Quantitative models of backward masking appeared almost as soon as computing technology was available to simulate them; and continued interest in masking has lead to the development of new models. Despite this long history, the impact of the models on the field has been limited because they have fundamental shortcomings. This paper discusses these shortcomings and outlines what future quantitat...

Although the literature has provided steps in the right direction, conceptual shortcomings still exist in the cross-hauling adjustment methods that are currently being applied in the literature. This paper represents an attempt to 1) characterize the cross-hauling adjustment methods that exist in the literature; 2) identify the shortcomings that exist with the most widely applied method, CHARM;...

Tunisia’s tax system has undergone significant structural reforms over the last several decades. Even so, its structure exhibits some major flaws, shortcomings that spill over to and affect the performance of the overall Tunisian economy. Further, the tax system continues to underperform in some fundamental ways, ways that also affect the rest of the economy. Finally, the structure of the Tunis...

An important task in object recognition is to rst identify the boundaries of the objects in the input image. Several neural networks have been proposed to perform edge detection and boundary segmenta-tion. Among them, Grossberg and Mingolla's Boundary Contour System (BCS) seems promising because it is able to complete missing object boundaries. Although BCS has been shown to work well on synthe...

REST protocol has gained great popularity as a communication in the various areas such as web service and IoT devices. However, the current RESTful web service has shortcomings in the authentication process. We developed an ID-based authentication algorithm to achieve a secure and stateless RESTful web service. ID-based authentication process allows a server to handle the client’s request by ac...

BACKGROUND As one of the most important components of harm reduction strategy for high-risk groups, following the HIV epidemics, Methadone Maintenance Treatment (MMT) has been initiated in prisoners since 2003. In this paper, we aimed to assess the advantages and shortcomings of the MMT program from the perspective of people who were involved with the delivery of prison healthcare in Iran. ME...
