Linguistic Variation across Research Sections of Pakistan Academic Writing: A Multidimensional Analysis
No full textWith the concept of language variation, it has become utmost important to analyze linguistic patterns across register. Pakistani academic writing like other registers in Pakistan is an area that still seeks the attention of the researchers and linguists. This target register needs to be fully described in terms of linguistic characteristics to strengthen the distinct identity of Pakistani academic writing as a register. The present research strives to explore linguistic variation across research sections of Pakistani academic writing as a register along with five new textual dimensions explored through the technique of Multidimensional analysis (Azher & Mehmood, 2016). The research is based on the corpus of 235 M. Phil and PhD research dissertations taken from different universities all over Pakistan. The corpus was further divided into five research sections and was tagged for 189 linguistic features. The ANOVA results on variation among research sections indicate that there lie statistically significant differences among research sections of Pakistani Academic Writing on all the new textual dimensions.</jats:p
A novel simulated annealing trajectory optimization algorithm in an autonomous UAVs-empowered MFC system for medical internet of things devices
No full textThis article investigates a new autonomous mobile fog computing (MFC) system empowered by multiple unmanned aerial vehicles (UAVs) in order to serve medical Internet of Things devices (MIoTDs) efficiently. The aim of this article is to reduce the energy consumption of the UAVs-empowered MFC system by designing UAVs' trajectories. To construct the trajectories of UAVs, we need to consider not only the order of SPs but also the association among UAVs, SPs, and MIoTDs. The above-mentioned problem is very complicated and is difficult to be handled via applying traditional techniques, as it is NP-hard, nonlinear, non-convex, and mixed-integer. To handle this problem, we propose a novel simulated annealing trajectory optimization algorithm (SATOA), which handles the problem in three phases. First, the deployment (i.e., number and locations) of stop points (SPs) is updated and produced randomly using variable population sizes. Accordingly, MIoTDs are associated with SPs and extra SPs are removed. Finally, a novel simulated annealing algorithm is proposed to optimize UAVs' association with SPs as well as their trajectories. The performance of SATOA is demonstrated by performing various experiments on nine instances with 40 to 200 MIoTDs. The simulation results show that the proposed SATOA outperforms other compared state-of-the-art algorithms in terms of saving energy consumption.The author would like to thank Prince Sultan University for their support.

Investigating Content and Language Integration in an EFL Textbook: A Corpus-Based Study
No full textThis research evaluates an English language textbook from CLIL perspective. For this purpose, an intermediate level
(grade-11) English language textbook has been selected and analyzed utilizing Coyle’s conceptual framework of 4Cs
(i.e. content, cognition, communication and culture).Content, communication, and culture have been explored through a
checklist, whereas cognition has been explored by developing a corpus from the questions given in the exercises of
the textbook and analyzing in the light of Bloom’s taxonomy. The results reveal certain breeches between CLIL
features and the textbook’s contents. Layout, learning outcomes, organization of the content, subject matter,
authenticity of the text, exercises, and focus on language skills does not seem to match with CLIL perspectives.
Listening and speaking skills are observed to be ignored. Moreover, the exercises do not seem to foster critical
thinking and interaction between students and teachers. Most of the questions are observed covering only first two
levels (i.e. knowledge and comprehension) of Bloom’s taxonomy. The study concludes that CLIL principles are not
integrated in the textbook. Therefore, the textbook is not suitable to an ESL/EFL setting
A Comparative Corpus-based Analysis of Collocational Patterns in Self and Other-translators
No full textWith the dawn of post-colonialism and a surge in migrations, several bilingual authors started translating their original texts into the target language. As a result, translation studies started distinguishing it from other-translations owing to its special status based on various extra-linguistic features. Consequently, now it goes by the term self-translation studies (Anselmi, 2012) -a field of its own. However, none of the studies have distinguished self and other-translations at the basic linguistic level. This study aims to trace and compare the patterns of collocations in other-translations and self-translations with reference to non-translated texts. For this purpose, a corpus-based on a monolingual comparable model (Baker, 1993) and consisting of three further sub-corpora i.e. other-translators, self-translators,and Pakistani writersis used. The lexical collocations model proposed by Benson et al. (1997) provides a theoretical framework for this study. The sub-corpora are tagged by TagAnt 1.2.0 and treated further using AntConc 3.5.8. The findings of the study reveal that self-translators employ more collocate types and they are more homogeneously distributed around a single node in comparison to the other-translators. The results are significant for the theoretical understanding of self-translations and invite more investigations at the linguistic level to set apart the features of the two categories

TRNSYS simulation of a solar cooling system for the hot climate of Pakistan
No full textCooling is a basic need for buildings in hot and sunny climates. In most countries the major source of cooling is electrical powerbased. During summer in hot climates there is an increase in electricity consumption due to cooling load. Pakistan is facing anelectricity shortage crisis, which becomes worse in summer due to the high demand for cooling. The annual average insolationfor Pakistan is 5-6 kWh/m2/day, reaching 6-8 kWh/m2/day in summer with sunshine of 10-13 hours a day, which gives suitableconditions for solar powered cooling system operation. TRNSYS software provides the possibility to simulate a complete solarair conditioning system integrated with a building. In this study, TRNSYS is used to model an absorption chiller operated by hotwater from an evacuated tube collector. It is found that, with a hot water storage tank, a collector area of 12 m2 is sufficient tomaintain the temperature in a room in a typical house at or below 26°C during the cooling season
