Loss Identification using Inverse Thermal Modelling in Cage Induction Motor
Induction motors play a key role in moving the wheel of the modern industry with ever increasing demand and need of high performance and more efficient electric machines. To meet this ever increasing demand, this thesis covers the base of it i.e. losses occurring in the induction motor and thermal modelling of motor on the basis of the losses. In order to compute the iron losses, COMSOL Multiphysics has been put to use which is a very useful for vast analysis on the basis of Finite Element Analysis. A quasi 3D model of the induction motor is built in COMSOL to compute the losses occurring in the stator and rotor of the induction motor. These losses are then put to further application by building 3D thermal model of the same motor in COMSOL Multiphsics for modelling the thermal behavior of the machine. In order to validate the theoretical work, experiments have been conducted on actual machine. In order to get vast practical data of temperature from the motor, a dedicated printed circuit board embedded with PT100 RTDs is designed to be put inside the stator of the machine while manufacturing. In the end, a detailed comparison of the simulated and measured results is done for deep understanding of the loss and thermal behavior phenomena. The experimental results validated the thermal modelling for the simulated losses by showing strong coherence with the simulated results. The temperature rise data from sensors sheet inserted in the stator came out to be very useful in validating the results and in using the inverse thermal computation of losses
Load Distribution Factors for Skewed Composite Steel I-Girder Bridges
The concept of load distribution factors have been used in bridge design for many decades as a simplified method to estimate load effects on bridge members. It enables bridge engineers to consider the transverse and longitudinal effects of truck wheel loads as two separate phenomena and thus simplifying the analysis and design of new bridges as well as for the evaluation of the load carrying capacity of existing bridges. Existing bridge design codes do not provide sufficient guidance to bridge engineers regarding the accurate assessment of load distribution factors for skew composite bridges. Thus leads to an extremely conservative design in some cases and to unsafe design in others, since these factors do not represent the actual behavior of the bridge structure. The presence of skew angle makes the analysis and design of composite slab-on-girder bridges much more complex in comparison to straight bridges. Over the past decade, several authors have drawn attention toward the steel I-girder twisting placed over highly skewed supports. These rotations are larger at the obtuse corners and difficult to predict due to the uneven load distribution across the bridge superstructure. In addition to girder twisting, skewed bridges can also lead to increased lateral flange bending stresses as well as increased shear and end reactions at girder obtuse corners that subsequently results in the reduction of girder shear and end reactions, and even possibly undesirable uplift in girders at the acute corners of the bridge

Relationship between the variables under study is explored using structural equation modeling as a statistical tool. Positive association were revealed among involvement related to job, commitment to an organization with satisfaction related to a job during the study on the other hand insignificant connection among commitment in relation with the organization, satisfaction in relation with the job itself and intentions toward turnover were partially maintained by the findings. Model used in the present investigation is tested empirically and fit indices confirm it. Keywords: Organizational commitment, Job Involvement, Job satisfaction, Labor turnover intention, Structural Equation Modeling
Determinants of Human Development Disparities: A Cross District Analysis of Punjab, Pakistan
Human development is the primary objective of all developing
economies of the world. It has great importance in social planning.
Every individual, society and nation wants a prosperous life. Different
instruments are used, investments are undertaken and different policy
frameworks are designed to achieve this target. Human development is a
process to enlarge the choices of people. So, the definition of human
development is very broad, but people have three basic and essential
choices which are acceptable at every level of development. First,
people always have desire to live a long and healthy life. Second, they
have desire to expand their knowledge. Third, people have desire to
access the resources needed for a decent standard of living [UNDP

ANALISIS KONSEPTUAL MENGENAI MUSIBAH DALAM PANDANGAN ISLAM
Dalam perjalanan hidupnya, tentu manusia akan menghadapi suatu musibah yang akan dapat berdampak pada fisik dan rohani dari seorang manusia. Apabila ia tidak mampu untuk bertahan dalam keimanan kepada Allah swt., maka ia dapat terpuruk dan menjadi seorarng yang berputus asa. Namun, apabila manusia yakin bahwa musibah yang menimpanya tidak lain adalah bukti bahwa Allah swt. memberikan pelajaran kepadanya agar ia kembali atau tetap di jalan yang benar yaitu jalan menuju Rabbnya. Tujuan dari penulisan ini adalah memberikan pemahaman mengenai musibah dalam pandangan Islam. Adapun hasil dari pembahasan pada artikel ini yaitu bahwa musibah merupakan segala sesuatu yang menimpa manusia baik itu berupa kesenangan atau kenikmatan duniawi maupun kesusahan, kemalangan, atau peristiwa-peristiwa yang tidak mengenakan dan tidak diinginkan seperti terjadinya bencana pada manusia dan bencana pada alam semesta. Adapun musibah itu sendiri dapat disebabkan karena beberapa hal seperti karena kehendak Allah swt., akibat perbuatan dari manusia, serta karena telah tertulis dalam kitab (Lauhul Mahfuzh). Selanjutnya, musibah dapat dibedakan berdasarkan objeknya, akibat yang ditimbulkannya, serta tujuannya. Kemudian, setiap manusia yang ditimpa musibah hendaklah ia bersabar, bersyukur, serta bertawakkal kepada Allah swt. sebab terdapat banyak hikmah dibalik musibah yang ia alami
