Intention to Leave - Organizational Commitment Relation : Moderating Effect of Job Performance

Previous studies found that organizational commitment inversely related to intention to leave. Above relationship is found to be moderated by job, experience, gender and perfomance. Above findings are found to be significant in specific setting (environment, demographic factors, culture, etc.). So it is not 100% applicable in every settings even though above findings are accepted generally. This study is carried out in order to suit Sharp-Roxy Corporation Sdn. Bhd Setting. At the end of the study it was found that organizational commitment inversely related to intention to leave, but above relationship is not significantly moderated by job perfomance

Mechanical Properties Evaluation of 3D Printed PETG and PCTG Polymers

3D printing is also known as additive manufacturing (AM) which has become a popular manufacturing trend over the years. Due to its unique advantages of fast production rate, ability to create complex geometrical features, toolless manufacturing and many more attracts various industries from Aerospace to general cosmetics. Along with the advancement in material science, various polymers including Polylactic Acid (PLA), Polyethylene terephthalate glycol (PETG) and many more are available for 3D printing. Due to the wide range of applications in PLA, it is necessary to improve its toughness to make it more suitable by adding Poly Cyclohexylenedimethylene Terephthalate glycol (PCTG) elastomer in PLA which can be effective to improve it. In the present study, the mechanical properties of PETG and PCTG polymers have been derived from different mechanical testing to understand the material behavior. All the polymer samples for mechanical testing was printed using Fused Deposition Method (FDM) which is the most popular 3D printing strategy. The mechanical testing used in current study to evaluate material properties include Tensile Testing, Compression Testing, Impact Testing and Flexure Testing. Fourier Transform Infrared Spectroscopy (FTIR) was also performed to evaluate compound analysis of PCTG polymer. The properties obtained after test conduct such as Ultimate Tensile Strength (UTS), Yield Strength (YS), Elastic Modulus (E), Elongation, Impact energy are evaluated and compared. Temperature has a significant impact on mechanical properties of polymeric materials. Thus, in Chapter 2, we have conducted all mechanical testing on PETG polymer samples at different temperatures in range between 230oC to 270 oC with increment of 10 oC to understand behavior of PETG with temperature variation. Along with temperature, printing parameters such as nozzle temperature, raster orientation, print speed, bed temperature, also different manufacturing brands can affect the mechanical properties of polymer. In Chapter 3, we have given this parametric impact on mechanical properties of PCTG polymer. Two different manufactured PCTG filaments (Lodesign and Essentium) were printed at 260° C of the nozzle temperature, 75°C bed temperature, a print speed of 40 mm/s, raster orientation of 45°, and a nozzle size of 0.4 mm. The annealing was also performed on Essentium sample at 100°C before mechanical testing to study the heat treatment impact on mechanical properties

Correlation between physical properties and flowability Indicators for fine powders

Approximately 80% of pharmaceutical products and the ingredients required for their manufacture are in powder form. The solid dosage form (tablets and capsules) is manufactured by either dry-blending of fine powder ingredients or combining the ingredients in a wet granulation step, followed by drying. Arching, ratholing, caking, segregation and flooding are some of the commonly encountered flow problems in the handling of fine powders. These problems lead to losses worth thousands of dollars at production scale. Poor powder flowability is a consequence of the combined effects of many variables, including improper equipment design, particle size, size distribution, shape, moisture content and surface texture. In the present work, a systematic study has been performed to determine the relationship between the flowability of fine powders and their physical properties of mean size and size distribution, density and shape. Flowability studies were done on six different powders: the NutraSweet® Brand sweetener (aspartame), Respitose ML001, Alpha-D-Lactose monohydrate, the pharmaceutical binder Methocel (R) F50 Premium Hydroxypropyl methylcellulose- HPMC, a placebo pharmaceutical granulate, and common pastry flour. Scanning electron microscopy (SEM) and stereomicroscopy were used for particle shape and size analysis. Particle size distribution was determined using the laser light scattering technique. Powder flowability was measured using shear strength, angle of repose, and tapped-to-bulk density measurements. A novel method of measuring the dynamic angle of repose using electrical capacitance tomography (ECT) was developed. Analysis of the images from microscopy revealed that the particles of aspartame and HPMC powders were elongated, the particles of ML001, pastry flour and lactose monohydrate powders were irregular, and the particles of placebo granulate were nearly spherical. Particle size was found to be the most reliable indicator of powder flowability, with decreasing particle size corresponding to lower flowability; however other parameters such as particle elongation and irregularity, were also found to have an influence on powder flowability. Although HPMC and pastry flour had similar particle sizes, they exhibited differences in flowability. This can be explained by the greater irregularity of the flour particles. Particle irregularity may cause mechanical interlocking between the particles, thus reducing powder flowability. ECT was found to be a promising non-intrusive tool for the measurement of the dynamic angle of repose. Unlike other methods for the measurement of dynamic angle of repose, the results obtained from ECT were not influenced by the effect of end caps. The present technique could be used by pharmaceutical industries in process analytical technology (PAT) for the detection and elimination of potential flow problems early in the manufacturing process

Review on AMES-Cloud Using Preservation, Fetching and Decisive Video Streaming Over Cloud Computing

The video traffic demands are increasing over a mobile network through wireless link cannot corporate with the demand of video traffics. The increasing traffic demand is accounted by video streaming and downloading. Hence, there is a gap between link capacity and traffic demands along with the time varying condition which is result in the poor quality of video streaming service over a mobile network such as sending long buffering time and intermittent disruptions due to limited bandwidth and link condition. By leveraging cloud computing technology, we propose a new mobile video streaming framework which has two main parts : Efficient social video sharing and Adaptive mobile video streaming which built a private agent which provides video streaming service for each mobile user in the network efficiently. To demonstrate its performance we implement a prototype of AMES-Cloud framework. Thus, it is crucial to improve the video quality service of streaming while using the computing resource and networking efficiently and also provides preservation over cloud computing.

Evaluation of Functional Data Models for Database Design and Use

The problems of design, operation, and maintenance of databases using the three most popular database management systems (Hierarchical, CQDASYL/DBTG, and Relational) are well known. Users wishing to use these systems have to make conscious and often complex mappings between the real-world structures and the data structuring options (data models) provided by these systems. In addition, much of the semantics associated with the data either does not get expressed at all or gets embedded procedurally in application programs in an ad-hoc way. In recent years, a large number of data models (called semantic data models) have been proposed with the aim of simplifying database design and use. However, the lack of usable implementations of these proposals has so far inhibited the widespread use of these concepts. The present work reports on an effort to evaluate and extend one such semantic model by means of an implementation. It is based on the functional data model proposed earlier by Shipman[SHIP81). We call this 'Extended Functional Data Model' (EFDM). EFDM, like Shipman's proposals, is a marriage of three of the advanced modelling concepts found in both database and artificial intelligence research: the concept of entity to represent an object in the real world, the concept of type hierarchy among entity types, and the concept of derived data for modelling procedural knowledge. The functional notation of the model lends itself to high level data manipulation languages. The data selection in these languages is expressed simply as function application. Further, the functional approach makes it possible to incorporate general purpose computation facilities in the data languages without having to embed them in procedural languages. In addition to providing the usual database facilities, the implementation also provides a mechanism to specify multiple user views of the database
