Factors Affecting Software Cost Estimation in Developing Countries
Ali Javed,Mirza Ahsan Ullah,Aziz-ur-Rehman
International Journal of Information Technology and Computer Science , 2013,
Abstract: Cost is the main driving factor for all projects. When it is done correctly, it helps in the successful completion of the project. In this research we have discussed various factors that affect the estimation procedure. These include team structure, team culture, managerial style, project type (Core application or integrated application), client’s working environment. Accurate estimation is far difficult in developing countries where most of the organizations follow local standards. These inaccurate estimations lead to late delivery, less profit or in worst case complete failure. Software requirement gathering, development, maintenance, quality assurance and cost of poor quality are major groups responsible for overall cost in software production process. The exact proportion among them varies significantly in consecutive software releases, which is caused by many factors. The ever increasing need for the reliability of the software systems, especially mission critical applications in the public safety domain, raises the bar for the accuracy of prediction and estimation techniques. The accuracy of estimations in many areas brings about more concerns regarding techniques already used in the software industry. Widely deployed techniques, such as Wideband Delphi method, stress the engineering and technical aspects of the process of how estimates are prepared.
Comparative Analysis of Different Fabric Defects Detection Techniques
Ali Javed,Mirza Ahsan Ullah,Aziz-ur-Rehman
International Journal of Image, Graphics and Signal Processing , 2013,
Abstract: In last few years’ different textile companies aim to produce the quality fabrics. Major loss of any textile oriented company occurs due to defective fabrics. So the detection of faulty fabrics plays an important role in the success of any company. Till now most of the inspection is done using human visual. This way is too much time consuming, cumbersome and prone to human errors. In past, many advances are made in developing automated and computerized systems to reduce cost and time whereas, increasing the efficiency of the process. This paper aims at comparing some of these techniques on the basis of classification methods and accuracy.
An Approach Towards Customized Multi-Tenancy
Muhammad Fahad Khan,Mirza Ahsan Ullah,Aziz-ur-Rehman
International Journal of Modern Education and Computer Science , 2012,
Abstract: Multi-tenant applications are usually cloud based software services which can serve different users at the same time. This is done using single instance of applications by sharing hardware, infrastructure, data storage and virtualization. To achieve multi tenancy different approaches are there at every layer (Application, Data, hardware).Multi tenancy helps to minimize the effort needed for deployment and maintenance with an adequate level of security and privacy. Now a day the work is going on custom multi tenancy by sharing everything at each layer. This paper will describe the techniques of multi tenancy and how security, flexibility and scalability relate to each other when it comes to multi tenancy for customization.
A Scheme of Combined Quad/Triangle Subdivision Surface
Ahsan Ullah,Koichi Harada
Asian Journal of Information Technology , 2012,
Abstract: Subdivision has become a staple of the geometric modeling community allowing coarse, polygonal shapes to represent highly refined, smooth shapes with guaranteed continuity properties. Unlike regular surface spines, such as NURBS, subdivision surface can handle shapes of arbitrary topology in a unified framework which is important in designing aesthetically pleasing shapes. This study presents a scheme of combined quad/triangle subdivision surface that has many important features resulting it s superiority over some other existing methods like individual triangle or individual quadrilateral subdivision schemes. In general, the scheme produces nicer surface for combined quad/triangle meshes.
Sedimentology of Marl and Marly Limestone Sequence of Upper Cretaceous Kawagarh Formation from Northern Kalachitta Range, Attock Hazara Fold and Thrust Belt, Pakistan  [PDF]
Saif Ur Rehman, Khalid Mehmood, Muhammad Fahad Ullah, Naveed Ahsan, Faisal Rehman, Tariq Mahmood, Mahboob Ahmed
Open Journal of Geology (OJG) , 2019, DOI: 10.4236/ojg.2019.91001
Abstract: Upper Cretaceous Kawagarh Formation is well exposed in the Attock Hazara Fold and Thrust Belt (AHFTB) and shows significant lateral and vertical variations in lithology. The present work deals with the sedimentological studies of marl and marly limestone sequence of Kawagarh Formation exposed at the Bagh Neelab, Ghariala north and Sojhanda villages in Northern Kalachitta Range. Detailed petrographic studies of marly limestone and hard marl substrate show that planktons and oysters are the main skeletal constituents of studied samples and clay and detrital quartz mainly composed the non skeletal fraction. X-Ray diffraction analyses of selected marl samples confirm the petrographic data. On the basis of skeletal and non skeletal content, two microfacies—marl microfacies and Planktonic microfacies are constructed. The faunal content, their paleoecology and detrital content of microfacies suggest that marl and marly limestone sequence of Kawagarh Formation was deposited over the mid and outer ramp settings.
Gendering Cross-Border Networks in the Greater Mekong Subregion: Drawing Invisible Routes to Thailand
AKM Ahsan Ullah,Mallik Akram Hossain
ASEAS : ?sterreichische Zeitschrift für Südostasienwissenschaften , 2011,
Abstract: This article discusses human tra cking within the Greater Mekong Subregion (GMS) in relation to the strengthened inter-state economic and infrastructural co-operation and connectivity, taking the life history of sex workers in Thailand into account. Over the last decades, Thailand became known as a hub of entertainment sectors. Tra ckers often use socio-economic integration in the GMS to their advantage. A large number of tra cked women ends up in the Thai entertainment industry doing sex work in con ned conditions similar to slavery. Poor women are often lured by false promises of well-paid jobs abroad and pay exorbitant fees to agents for such an opportunity. Intermediaries introduce family members to agents who promise to make arrangements for the relevant documentation and transportation across borders. Tra ckers use their own marked routes to transport their prey which are more invisible than generally could be imagined. ----- Der vorliegende Beitrag betrachtet den Menschenhandel in der Greater Mekong Subregion (GMS) unter Berücksichtigung der St rkung zwischenstaatlicher wirtschaftlicher und infrastruktureller Kooperation und Vernetzung. Dabei nimmt er Lebensgeschichten Prostituierter in Thailand genauer unter die Lupe. Im Laufe der Jahre wurde Thailand als Drehscheibe des Unterhaltungssektors berühmt. Es ist jedoch weitgehend unbekannt, dass eine Gro zahl der Opfer des Menschenhandels in der Sexarbeit und in der Sklaverei hnlichen Arbeitsverh ltnissen landet. Menschenh ndler nützen die sozio konomische Integration in der GMS zu ihrem Vorteil. Diese Studie zeigt, dass von Armut betro ene Frauen in der Regel durch falsche Versprechungen gut bezahlter Arbeitspl tze ins Ausland gelockt werden und für solche Gelegenheiten exorbitante Gebühren an ihre Agenten bezahlen. Vermittler bringen Familienmitglieder und Agenten zusammen, welche die entsprechenden Unterlagen vorbereiten um den Transport über den Grenzübertritt m glich zu machen. Menschenh ndler nutzen eigene markierte Routen, um ihre Beute zu transportieren – Wege die unsichtbarer sind, als man sich allgemein vorstellt.

Intelligent Control and Automation (ICA) , 2019, DOI: 10.4236/ica.2019.104010
Hydroponic System is a system in which farmers cultivate different plants without utilizing the soil. The authors have proposed IoT system that monitors and controls all parameters of hydroponic system like water level, pH, humidity and temperature through mobile application. In proposed system, the authors have used an ESP32 micro-controller that is controlled pump. The pump will draw water from a reservoir which is connected to a regular water line. If the water level of the reservoir falls down to a certain level, the system will send an SMS to the Farmer. The farmer can control the water line and make the reservoir full by mobile application. An LDR and DHT11 humidity sensor is used to control the light and temperature of the farm. In system, we also used pH sensor where pH sensor is a scientific instrument that measures the hydrogen-ion activity in water-based solutions and indicating its acidity or alkalinity expressed as pH.

Abstract: The study was conducted to compare the superovularoty response of buffalo in winter and summer. Four adult buffaloes were treated with follicle stimulating hormone (FSH) during winter (November to January) and three buffaloes in summer (June. and July). Superovulatory response was determined by estimating the number of corpora lutea (CL) palpated per rectum on day 6 of the oestrus cycle (oestrus = day 0). The number and quality of embryos collected were also studied. A better ovarian response was observed in winter (5.8+0.3 CL) than in summer (2.7+1.2CL) (P<0.05). A mean (+SE) 1.3+0.9 embryos were recovered during winter compared to 0.5+0.4 embryos in summer. All the embryos recovered in winter were of good quality whereas only fair quality embryos were recovered in summer. Two pregnancies were achieved in winter after transfer of three embryos to three synchronized recipient buffaloes. The study showed a better ovarian response of buffalo to FSH in winter.
