Generic programming is a mechanism for re-using code by abstracting specific types used in classes and programs. In this paper, we present a mechanism for adding generic programming in dynamically typed languages, showing how programmers can benefit from generic programming. Furthermore, we enhance the expressiveness of generic programming with reverse generics, a mechanism for automatically deriving new generic code starting from existing non-generic one. We implemented generics and reverse generics in Pharo Smalltalk, and we successfully used them to solve a problem of reusing unit test cases. this helped us to identify a number of bugs and anomalies in the stream class hierarchy.
this paper presents an alternative method for solving the problem of finite transducers using gene expression programming (GEP). Each individual in the GEP system represents a Mealy machine with outputs for each state...

Calixarenes are good carriers for cations, anions and neutral molecules because they are cyclic, can be easily derivatized, and can create molecular sizes of different sizes. Due to these properties, they have a very wide application area [1]. the use of calixarenes obtained by functioning with different functional groups in the transport and release of drugs takes place in the literature. In this study, p-tert-butylcalix[4]arene derivatives with p-nitrobenzyl functional group and then nanofibers of those new synthesis was obtained by using electrospinning method. Produced calixarene nanofiber primary breast cancer cell application [2,3].

programming is taught as foundation module at the beginning of undergraduate studies and/or during foundation year. Learning introductory programming languages such as Pascal, Basic / C (procedural) and C++ / Java (object oriented) requires learners to understand the underlying programming paradigm, syntax, logic and the structure. Learning to program is considered hard for novice learners and it is important to understand what makes learning program so difficult and how students learn. the prevailing focus on multimedia learning objects provides promising approach to create better knowledge transfer. this project aims to investigate: (a) students' perception in learning to program and the difficulties. (b) effectiveness of multimedia learning objects in learning introductory programming language in a face-to-face learning environment. Copyright 2009 ACM.

Since maritime transportation is the most cost-efficient way to transport goods, it has experienced a significant growth in the last few decades due to global trade and economic development. Consequently, CO2 emissions accounting for this sector have also risen. the purpose of this paper is to estimate and minimize the amount of CO2 emissions generated while a vessel is in the hoteling phase, both from the perspective of the vessel and the cranes servicing it, while providing an insight into the share of emissions from both sources and the potential solutions to reduce them. A Mixed Integer programming model was formulated using General Algebraic Modeling System (GAMS). the results of the study show that the quay crane emissions play a significant role of the total emissions during the hoteling phase, affecting quay crane workload distribution and bay allocation, and they should be taken into account when trying to minimize emissions at the terminal operations.
We present a study of the university post-enrolment timetabling problem, proposed as Track 2 of the 2007international Timetabling Competition. We approach the problem using several techniques, particularly local sear...

One year ago in our previous article we declared that the education of programming for the informatics students at the University must contain the whole process of the development. It was not changed as our experiences that the majority of the students are only interested in creating an operative code somehow. In that article we presented a solution which tried to assist to solve this problem. Our excel-based guidance helped to follow the steps of the whole programming process. We took into consideration the feedbacks, and performed the improvements. this new application supports the complex data types, more sub-tasks and now it is available on the web. this article presents the new web-based system and reports about its welcome.
