Accurate frequency determination is an usual task in many scientific fields including medical physiological measurements like EEG, ECG and also the determination of the fundamental frequency in acoustical signals. Beyond the pure computational problem the difficulties are connected with ambiguities in the definition of frequency. In the strongest mathematical sense frequency is only defined in ...

A study of the use of and attitudes towards the telephone by persons with stuttering impairment is presented. Data was collected by survey (postal questionnaire). Results indicate that making calls may be more problematic than answering them. Avoidance-like behaviours were more prevalent amongst younger adult stutterers than their older counterparts. Severe stutterers use the telephone least. M...

The use of stainless steel 316L (SS 316L) in the medical, marine, aerospace, bio-medical, and automobile sectors increases rapidly. Electrochemical micro-machining (ECMM) is appropriate method for machining SS due to its burr-free surface, no residual stress, high precision. However, some limitations are found using strong electrolytes, such as HCl, H2SO4, KOH, NaNO3, NaCl, which reportedly fac...

Salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. Most benign tumors occur in the parotid gland. Pleomorphic Adenoma is the most common type. Basal Cell Adenoma is a subtype of the Monomorphic Adenoma with rare occurrence. Proper diagnosis and clinical evaluation by the use of radiography can lead the physician to the best t...

The proper modeling of nonequilibrium gas dynamics is required in certain regimes of hypersonic flow. For inviscid flow this gives a system of conservation laws coupled with source terms representing the chemistry. Often a wide range of time scales is present in the problem, leading to numerical difficulties as in stiff systems of ordinary differential equations. Stability can be achieved by us...

In recent years face recognition has received significant attention from both research communities and society of network multimedia information access. Major progress and immense range of biometric applications in banking, national identity, law enforcement, immigration, and logical access control have projected face recognition technology into the spotlight. Though earlier, simple geometric m...

The difficulties inherent in trying to pursue face to face professional development opportunities have traditionally made it difficult for teachers to access professional learning. Today, given the proper communication tools, teachers can become involved in meaningful professional learning without the restrictions imposed by time and place. This paper examines findings from the analysis of a gr...

The "Urban Village Approach" is one of the most appropriate ways to eliminate recent urban problems, including social, environmental, cultural, and economic shortcomings. Although the urban village approach is generally proper to resolve these types of flaws, its combination with the democratic concept of urban design can definitely provide more effective solutions. So at first, this ...
