This paper presents a novel review on Embedded Systems (ES) Codesign methodologies with a focus on the possible application of Artificial Intelligence (AI) methods to improve conventional ES Codesign flows and especially to deal with Intelligent Embedded Systems (IES) which represent a novel and promising generation of embedded systems. IES have the capacity of reasoning about their external environments and adapt their behavior accordingly. Such systems are situated in the intersection of two different branches that are the embedded computing and the intelligent computing.\nDespite, the wide spread of such systems, some design challenging issues are arising. Designing a resource constrained software and at the same time intelligent is not a trivial task especially in a real time context. To deal with this dilemma, embedded systems researchers have profited from the progress in Semiconductor technology to develop specific hardware to support well AI models and render the integration of AI with the embedded world a reality.\nComparatively to back-end activities which are more automated, we think that requirements engineering activities which are more interactive and experience human-guided are a fertile area where AI methods can be applied efficiently to assist ES analysts to comprehend and collect changing customers requirements, establish project scheduling and performance/risks estimations and making early multi-criterion decisions with regard to the most appropriate available methodologies and tools matching well the project objectives and constraints.\n.
Thanks to advances in agricultural technology applications and the increase in the use of design products, various methods can now be employed for seeding, the most important step in agricultural production. Broadcast seeding is one method that is largely preferred. However, the inability to distribute the seeds uniformly on the ground is the fundamental problem facing farmers. This study purpose was to provide a solution to this problem. The wheat seeds (Basribey-95) were broadcast-seeded with the aid of three different deflectors that look like a fish’s tail (flat, channeled, impacted deflector). At three different speeds (1-1.5-2 ms-1) and inclines (0-5-10%), seeding performance of the deflectors was observed. The data was obtained in a laboratory setting and statistically evaluated to provide a solution to the most fundamental problem in broadcast seeding.
This study assessed the bacteriological effluent qualities of abattoirs in Abakaliki zone, Southeast, Nigeria between March and September 2015. Wastewater samples were collected from the two abattoirs, from their point of discharge into surface water bodies with sterile sample bottles and transported to the Laboratory for bacteriological analyses. Bacteria species isolated were characterized and identified using standard microbiological and biochemical techniques. Antibiotic susceptibility study was carried out using Kirby Bauer disc diffusion method according to Clinical and Laboratory Standards Institute (CLSI). The result of the total heterotrophic bacteria count obtained from Nkwo - Ezzangbo abattoir ranges from 7.00 x 106 CFU/ml to 7.90 x 105 CFU/ml, While, the result of the total bacteria counts from Abakaliki abattoir ranges from 5.50 x 106 CFU/ml to 6.95 x 105 CFU/ml. Statistical analysis using ANOVA revealed that there was no significant difference at 0.05 level of significance in the total heterotrophic bacterial count obtained from the different sampling points from the two abattoirs Antibiotic studies showed that majority of the gram - negative isolates was sensitive to the antibiotics. while, resistance was obtained against augmentin, nalidixic acid for P. aeruginosa. E. coli had resistance against ceporex, septrin and nalidixic acid. While, the gram positive streptococci had resistance against cetriaxone and ampicillin. The presence of these multi-drug resistant strains of the isolated organism in abattoir effluents could act as a vehicle to disseminate antibiotic resistance to other bacteria. This emphasizes the need for proper treatment and safe disposal of abattoir effluents in the study area
The number of tourists visiting Kingdom of Saudi Arabia is increasing. But this increase is not commensurate with the number of guests accommodated in the Sheraton & Towers Hotel. This is due to large number of Hotels in the country. In view of this the management needs to review its marketing strategy on the Hotel as it is one of the international Hotels. This study aims to determine the variables that form the strengths, weaknesses, opportunities, and threats in management of this Hotel. The research employed a mixed- method approach is SWOT analysis. The population of the study included the top management involving several experts and authorities to validate specifically some related external environmental factors. The result from the analysis revealed that variables of the Hotel strength consisted of; the completeness of the room in the Hotel, the location of the Hotel’s proximity to the beach, the price adjustment, the promotion intensity, quality of service and competence of employees, incorporation with travel agents and package trips and vacations, wedding package and event. The weakness is that the Hotel location is not easily accessible. The opportunities is demonstrated by the stability and relative security, flexible government policies, development of information technology, and the preservation of natural resources in the environment around the Hotel. The threat identified include increasing growth rate of Hotels, community cultural hindrance prevent comfortable environment within the Hotel. The Hotel’s prospect for future growth and development. The paper suggested improving unique and interesting ornamentation in the development wedding chapel and restaurants, provide special rates to guests, improving the Hotel’s advertisement, additional cultural attractions among others will build on the existing strength of the Hotel.
