This paper, proposes a new algorithm for recognition of facial expressions, called ER7ST. Studied expressions are anger, disgust, fear, happiness natural, sadness and surprise. Proposed method is based on extraction of the essential objects, then finding of characteristic points positions of each object. Detected points slant and its average are calculated on the basis of fixed points. Mug database is considered as data source for training and testing. We collect set of images. ER7ST is designed to define the work area of face that contains characteristic expressions, which its centre is face centre and its dimensions are 8×16 supposed squares. ER7ST algorithm discovers the essential objects depending on the coordinate of minimum and maximum points of each object in defined area, considering the length of object is larger than the major-axis of formed ellipse on studied object. Object gradient is ranked between [-60, +60] degrees. Our algorithm detects Convex Hull points upon detected objects and then its slant is calculated. Slant vectors are formed; some calculations are done to be a good input to network. Net contains input, three hidden layers and output layer. After training on set of faces and testing on new data, the recognition rate was promising. Algorithm can be maintained with different types of images and it did not need to scale. Finally, recognition rate is ranked between 60% and 95%, experiments have shown that method was efficient and results were very encouraging in this field, especially network can be trained on new situations of expressions.

A geodesic is the real world analog of a straight line. Where a straight line on a flat piece of paper minimizes the distance between two points, a geodesic minimizes the distance between two points on any surface; be it flat or not.Supposing that we have a surface in spacegiven by the equation z = f (x, y).The search for a geodesic line on this surface, or more generally in the plan provided by an arbitrary metric, may be made by solving the coupled differential second orderequations of Euler-Lagrange system. More precisely, the search of the shortest path connecting two given points may be made by solving that system for a specific initial velocity. In this paper we determine the geodesic lines corresponding the metric of type g =(dx2 + dy2) for f (x, y) defines positive. Starting from a metric of this type, we determine the Euler- Lagrange system correspondence; its solutions are geodesics. We designed geodesics and the shortest path for the given metric and a specific function f (x, y). We will need to determine the appropriate initial velocity for the system's numerical resolution of two differential equations of second order. Therefore, we are providing a suitable method for this.

Finding correspondences automatically from a pair of un-calibrated images is a challenging phase in 3D reconstruction. Two proposed methods based on the existing SIFT and SURF key point detector and descriptor are introduced in this work to find correspondences automatically from high resolution pair of images for aerial scenes. The characteristics of the data set involved in this research in terms of size and the presence of affine transformation add more challenges in finding the set of desirable matches.

Mobile Ad-hoc network (MANET) is characterized with high mobility and frequent topology change. Routing in MANET should follow these constrains, otherwise, it can severely degrade the performance of MANET. Greedy perimeter stateless routing (GPSR) in MANET uses one-hop neighbor's location information to make the forwarding decision. GPSR uses proactive update method to distribute position information via periodic “beacon” messages (PMs). The increasing in accuracy ratio leads to high communication overhead that will be in the expense of network resources. To address this problem, this paper presents a simple and efficient updating algorithm using Dynamic Fuzzy Logic Controller and Mobility Prediction (DBUM). DBUM is constructed of two patterns to improve the accuracy of node's location information. DBUM algorithm is able to improve the accuracy of node's location information with less

Background: Pressure ulcer remains a significant problem in the healthcare system. In addition to the suffering it causes patients, it bears a growing financial burden. Although pressure ulcer prevention and care have improved in recent years, pressure ulcer still exists and occurs in both hospital and community settings. In Jordan, there are a handful of studies on pressure ulcer. This study aims to explore levels of knowledge and knowledge sources about pressure ulcer prevention, as well as barriers to implementing pressure ulcer prevention guidelines among Jordanian nurses. Methods: Using a cross-sectional study design and a self-administered questionnaire, data was collected from 194 baccalaureate and master’s level staff nurses working in eight Jordanian hospitals. From September to October of 2011, their knowledge levels about pressure ulcer prevention and the sources of this knowledge were assessed, along with the barriers which reduce successful pressure ulcer care and prevention. ANOVA and t-test analysis were used to test the differences in nurses’ knowledge according to participants’ characteristics. Means, standard deviation, and frequencies were used to describe nurses’ knowledge levels, knowledge sources, and barriers to pressure ulcer prevention. Results: The majority (73%, n = 141) of nurses had inadequate knowledge about pressure ulcer prevention. The mean scores of the test for all participants was 10.84 out of 26 (SD = 2.3, range = 5–17), with the lowest score in themes related to PU etiology, preventive measures to reduce amount of pressure/shear,and risk assessment. In-service training was the second source of education on pressure ulcer, coming after university training. Shortage of staff and lack of time were the most frequently cited barriers to carrying out pressure ulcer risk assessment, documentation, and prevention. Conclusions: This study highlights concerns about Jordanian nurses’ knowledge of pressure ulcer prevention. The results of the current study showed inadequate knowledge among Jordanian nurses about pressure ulcer prevention based on National Pressure Ulcer Advisory Panel guidelines. Also, the low level of nurses’ pressure ulcer knowledge suggests poor dissemination of pressure ulcer knowledge in Jordan, a suggestion supported by the lack of relationship between years of experience and pressure ulcer knowledge.

Mobile learning applications utilise the advantages of mobile technologies to increase learning opportunities, mainly on an anytime, anywhere basis. The advancement of mobile technology has facilitated the development of numerous applications to improve students’ learning experience and performance. Successful implementation of m-learning is highly dependent on learning context and environment awareness. This work presents a multiphase exploration of early phases responsible for defining and validating the m-learning context, and later phases based on context validation results achieved from the previous phases, involving the development and evaluation of a new m-learning context prototype. This new prototype proved to provide context-aware and ubiquitous learning services fulfilling several diverse user interaction levels and requirements.

Mobile Ad-hoc network (MANET) is the guiding technology of ubiquitous era and a cornerstone in the 4G communication architecture. MANET has limited resources and characterized with high mobility and frequent topology change. Routing in MANET should follow these constrains, otherwise, it can severely degrade the performance of MANET. Owing to Greedy routing (GFS) nature in MANET, a certain part of the MANET becomes congested before other parts. In such area the nodes have failed to forward packets in a timely manner or drop them, thus such nodes called Network Holes. This paper presents a simple and efficient enhanced GFS routing algorithm called Intelligent Fuzzy logic Greedy forwarding Scheme (IFGFS). IFGFS consider the De-congestion level of each mobile node as another selective metric besides distance. In order to validate our algorithm, we rely on a wide simulation experiments. The evaluation results showed the correctness of our new proposed algorithm the adaptive- congestion IFGFS which maximize the performance of the network.

Background. Recently, the percentage of older adults in developing countries has increased significantly. Objective. This study examined patterns and factors associated with primary health care services utilization in the past 1, 6, and 12 months. Method. A cross-sectional study design was used to collect data from 190 older adults in the Irbid governorate of Jordan. Results. Primary health care serviceswere used by less than half of the participants in the past 1month, by 68.4% in the past 6 months, and by 73.8% in the past 12 months. Primary health care (PHC) services use was associated with age, education level, tobacco use, chronic illnesses, perceived general health status today, a physical component summary score, employment, and perceived general health status in the past 6 and 12 months. The primary predictor of PHC services use at 1, 6, and 12 months was chronic illnesses (OR = 13.32), (OR = 19.63), and (OR = 17.91), respectively. Conclusion. Although many factors were associated with PHC service utilization, the strongest predictor of PHC service utilization was chronic illnesses
