Opis:
This article deals with an inventory model under a situation in which the supplier offers the purchaser some credit period if the purchaser orders a large quantity. Shortages are not allowed. The effects of the inflation rate on purchase price, ordering price and inventory holding price, time dependent deterioration of units and permissible delay in payment are discussed. A mathematical model is developed when units in inventory are subject to time dependent deterioration under inflation when the supplier offers a permissible delay to the purchaser if the order quantity is greater than or equal to a pre-specified quantity. Optimal solution is obtained and algorithm is given to find the optimal order quantity and replenishment time, which minimizes the total cost of an inventory system in different scenarios. The paper concludes with a numerical example to illustrate the theoretical results and interdependence of parameters is studied for the optimal solutions.

Opis:
Meeting the educational needs of students currently requires moving toward collaborative electronic and mobile learning systems that parallel the vision of Web 2.0. However, factors such as data freedom, brokerage, interconnectivity and the Internet of Things add to a vision for Web 3.0 that will require consideration in the development of future campus-based, distance and vocational study. So, education can, in future, be expected to require deeper technological connections between students and learning environments, based on significant use of sensors, mobile devices, cloud computing and rich-media visualization. Therefore, we discuss challenges associated with such a futuristic campus context, including how learning materials and environments may be enriched by it. As an additional novel element the potential for much of that enrichment to be realized through development by students, within the curriculum, is also considered. We will conclude that much of the technology required to embrace the vision of Web 3.0 in education already exists, but that further research in key areas is required for the concept to achieve its full potential.

An eco-friendly and efficient one-pot synthesis of penta-substituted pyrrole derivatives via a four-component reaction of maldrum’s acid, arylglyoxal monohydrate, dimethyl but-2-yne-dioate and amines under catalyst-free conditions in an environmentally friendly medium is described. The simple experimental procedure, catalyst-free reaction conditions, short period of conversion, and excellent yields are the advantages of the present method. Good chemical yields have been achieved without the need for chromatography and recrystallization or other purification methods.

Reaction of 4-aminoquinolines with 4-nitrophenyl chloroformate have resulted in finding a novel transformation of 4-aminoquinolines to tricyclic (R,S)-3-methylazeto[3,2-c]quinolin-2(2aH)-ones. The structure of azeto-quinolinone was determined via spectroscopic and chemical methods. Various alcohols were used as nucleophiles to open the 1-azetinone ring to give the corresponding N-(quinolin-4-yl)carbamates in good yields. We also found a new and versatile one step synthesis of N-(quinolin-4-yl)carbamates by reacting 4-aminoquinolines with alkyl chloroformates in the presence of anhyd K2CO3 in acetonitrile.

Opis:
Two types of composite imprinted membranes, i.e., composite membrane comprised of D-Phe imprinted beads and D-Phe imprinted membrane or DCM and composite membrane comprised of L-Phe imprinted beads and L-Phe imprinted membranes or LCM, were synthesized by phase inversion technique after a uniform dispersion of beads within the polymeric solutions using simple physico-mechanical process. The assemblies of the prepared DCM, LCM and control membranes were employed in ultrafiltration for chiral separation of D, L-Phenylalanine racemate solution. DCM and LCM showed an improved adsorption capacity (0.334 mg g-1 and 0.365 mg g-1 respectively), and adsorption selectivity (2.72 and 2.98 respectively). However, the percent rejection of the template and counter enantiomer were lower than that of control membranes. Compared to control membrane, the DCM and LCM showed inverse permselectivity. These composite membranes having better adsorption and separation ability for Phenylalanine racemate solution will be suitable in the future for various other applications.

Opis:
With Growing Concerns About Voltage Profile And Power Factor At Distribution Networks, The Capacitor Banks Are Invariably Installed For Reactive Power Compensation. The Reactive Power Supplied By Capacitor Banks Is Proportional To Square Of Their Rated Loading Voltage. Capacitor Banks Eventually Increase The Loading Capacity Of Feeders, So As To Supply More Customers Through Same Line Section. Capacitor Banks Can Be Installed Anywhere On The Network. The Idea Of This Paper Is To Reduce Total Power Loss And Ensure Greater Availability Of Capacitor Bank Installed At 132 Kv Grid Station Qasimabad Hyderabad, For Reactive Power Compensation, Even Under Worst Conditions On Distribution System. This Is Achieved By Enhancing Its Location And Size. At Present Capacitor Bank Of Full Size, I.E. Of 1.21 Mvar Is Installed At 11 Kv Bus Of 132 Kv Grid Station Qasimabad Hyderabad. Moreover This Paper Suggests Small Sized Capacitor Banks That Would Be Installed At Different Feeders Instead Of One Large Size Capacitor Bank At 11 Kv Bus. The Voltage Profile And Power Losses With Present Sized Capacitor Bank And The Proposed Small Sized Capacitor Banks Are Compared In This Work. The Distribution Network Has Been Simulated By Using MATLAB .

Opis:
Software startup companies develop innovative, software-intensive products within limited time frames and with few resources, searching for sustainable and scalable business models. Software startups are quite distinct from traditional mature software companies, but also from micro-, small-, and medium-sized enterprises, introducing new challenges relevant for software engineering research. This paper’s research agenda focuses on software engineering in startups, identifying, in particular, 70+ research questions in the areas of supporting startup engineering activities, startup evolution models and patterns, ecosystems and innovation hubs, human aspects in software startups, applying startup concepts in non-startup environments, and methodologies and theories for startup research. We connect and motivate this research agenda with past studies in software startup research, while pointing out possible future directions. While all authors of this research agenda have their main background in Software Engineering or Computer Science, their interestin software startups broadens the perspective to the challenges, but also to the opportunities that emerge from multi-disciplinary research. Our audience is therefore primarily software engineering researchers, even though we aim at stimulating collaborations and research that crosses disciplinary boundaries. We believe that with this research agenda we cover a wide spectrum of the software startup industry current needs.
