Timetable creation is a very tedious and time consuming task; it takes lots of patience and man hours. Graph colouring technology helps to resolve this problem and introduces a practical timetabling algorithm capable of taking care of both hard and soft constraints effectively, used in an automated timetabling system for educational institutions. To resolve the complexity and to reduce the efforts of generating timetable manually, there are some other technologies like backtracking algorithm, Ant Colony Optimization, Bee Colony Optimization; Genetic Algorithm etc. are also available. Though these technologies provide the solution for timetable generation, these are slower and sometimes to provide the optimal solution there is a risk of losing the data when applied on large spaces. Graph colouring provides the exact solution for generating a conflicts-free timetable that too in optimal time.

With the fast development of big scale on-line social networks, on-line data sharing is becoming omnipresent daily. numerous info is propagating through on-line social networks similarly as every the positive and negative. Throughout this paper, we tend to tend to focus on the negative data problems just like the on-line rumors. Rumor block may well be a significant drawback in large-scale social networks. Malicious rumors might cause chaos in society and soought to be blocked as soon as potential once being detected. during this paper, we tend to propose a model of dynamic rumor influence reduction with user expertise (DRIMUX).Our goal is to cut back the influence of the rumor (i.e., the number of users that have accepted and sent the rumor) by block an exact set of nodes. A dynamic Ising propagation model considering every the worldwide quality and individual attraction of the rumor is given supported realistic state of affairs. to boot, altogether completely different from existing problems with influence reduction, we tend to tend to require into thought the constraint of user experience utility. Specifically, each node is assigned a tolerance time threshold. If the block time of each user exceeds that threshold, the utility of the network will decrease. underneath this constraint, we tend to tend to then formulate draw back as a network abstract thought drawback with survival theory, and propose solutions supported most probability principle. Experiments area unit implemented supported large-scale world networks and validate the effectiveness of our methodology.

In many developing countries Like India, most of the vapor compression based refrigeration, air conditioning and heat pump systems continue to run on halogenated refrigerants due to its excellent thermodynamic and thermo- physical properties apart from the low cost. However, the halogenated refrigerants have adverse environmental impacts such as ozone depletion potential (ODP) and global warming potential (GWP). This project is devoted to feasibility study of substitution of LPG which is locally available and comprises 24.4% propane, 56.4% butane and 17.2% isobutene. The LPG is cheap and possesses an environmentally friendly nature with no ozone depletion potential (ODP). It is used in Libya for cooking purposes. Experimental result showed that the LPG refrigerant with charge of 25g worked well under unloaded condition. It took 15 minutes to bring down evaporator temperature from 31 degree Celsiuse to 0 degree Celsius, in comparison to 90g R-134a which took 14 minutes for the same, under designed project set up. While LPG charge of 35g worked well under unload condition. It took 12 minutes to bring down the evaporator temperature from 31 degree Celsius to 0 degree Celsius in comparison to 90g R-134a which took 15 minutes for the same, under designed project. Ammeter continuously gave reading in the range of 0.6 A to 0.9 A and voltmeter as 210V while working with LPG as refrigerant in comparison to R134a in which ammeter gave reading of 1A and voltmeter as 220V. From here we can easily conclude that power consumed by compressor while working with LPG as refrigerant decreased considerably.

Although disposable diapers are superior in performance when compared with their reusable counterparts, a majority of Ethiopian parents use the latter for their babies. The key factors for this choice are limited availability (in rural areas) and high cost. This research proposes to reduce the cost of disposable diapers by making them semi-reusable. The objective was to prepare alternative inside absorbent core from indigenous materials and replace the core from normal disposable diapers after use (especially liquid insult). Such replacement would retain some functionalities of the disposable article while reducing the overall cost to parents. The materials investigated for producing the alternate core were eucalyptus bark and paper (A4 waste paper). It was found that treatment of alternative core material with a hydrophilic softener such as glycerin greatly enhanced the absorbent capacity. The average performance of diapers with the alternate core was comparable to those of original diapers. Then the alternative inside core performs better than commercial diaper. The remaining water volume was less than the commercial diaper. Similarly the weight of inside core and speed of absorption proved that was developed core than a commercial as compare to that is estimated that the cost of using normal disposable diaper is about 80 ETB per day which is probable cost of 17 ETB per day case of developed core. It may be concluded from this investigation that the abundant waste paper (from offices and universities in Ethiopia) is an excellent low-cost source to produce alternate absorbent core in baby diapers.
