We propose a fundamental frequency (F0) estimation method which is fast, accurate and suitable for real-time use. While the proposed method is based on the same framework as DIO [1, 2], it has two clear differences: it uses RMA (Recursive Moving Average) filters for attenuating high order harmonics, and the period detector is designed to work well even for signals which contain some higher harm...

Software-defined cognitive radios (CRs) use voice as a primary input/output modality and are expected to have substantial computational resources capable of supporting advanced speechand audio-processing applications. This chapter extends previous work on military speech applications (see, e.g., Ref. [1]) to cognitive-like services that enhance military mission capability by capitalizing on aut...

background: in most armies, clothes, equipment and weapons are designed according to the physical characteristics and anthropometric data of soldiers. objective: to study the anthropometric characteristics of iranian army force and their changes over recent years. methods: 12 635 iranian military personnel aged between 18 and 30 years with tenure of <10 years who were normally engaged in educat...

Sensor network facilitates monitoring and controlling of physical environments. These wireless networks consist of dense collection of sensors capable of collection and dissemination of data. They have application in variety of fields such as military purposes, environment monitoring etc. Typical deployment of sensor network assumes central processing station or a gateway to which all other nod...

The outlier detection is an important preprocessing routine that is required to ensure robustness of the sensory data analysis. Several factors make the wireless sensor networks (WSNs) especially prone to outliers. A sensor network is equipped with thousands of inexpensive, low fidelity nodes, which can easily generate sensing errors. Since these networks include a large number of sensors, the ...

Purpose: To investigate the factors affecting communicational skills of regimental commanders toward conscripts at an army introductory military training center in Tehran. Materials and Methods: The participants were 82 regimental commanders of the regiments and battalions of an introductory military training center. A 21-item questionnaire was used to collect the required data. Descriptive...
