...ASSAN, Kaida K HALID1 and Elias S AION INSPEM, Universiti Putra Malaysia, 43400 UPM Serdang, Malaysia 1 Department of Physics, Universiti Putra Malaysia, 43400 UPM Serdang, Malaysia (Received March 30, 2004; accepted September 3, 2004; published July 8, 2005) A simple, fast and accurate technique employing an open-ended coaxial sensor for the determination of the moisture content in oil palm fruit is presented. For this technique, a calibration equation has been developed based on the relationship between the measured moisture content obtained by the oven drying method and the phase of the reflection coefficient of the sensor for 21 fruits. The moisture content predicted by the sensor was in good agreement with that obtained using the standard oven drying method within Æ5% accuracy when tested on 145 different fruits samples.

Theoretical and empirical observation of the value of team processes provides the framework to personify our understanding of learning and present a model for teaching in higher education in Norway. We consider learning as a holistic process and one must appreciate its dynamics and be flexible and responsive to it. Moreover, such a view of the entire process necessitates an active communication with all stakeholders of the system and to make an integrative and coordinated effort to ensure availability of the required institutional resources, equitable distribution...

...changes the value of which in its turn, determines the index of refraction. The process is wavelength dependent: different wavelengths will induce different polarizations of the molecules and, as a result, and will be different. So, the index of refraction changes with wavelength: The phenomenon described above is known as the dispersion of light. Equation is the dispersion relation. For most of the materials, decreases with the wavelength (see figure1). This phenomenon is known as normal dispersion. The decreasing is more rapid at shorter wavelengths. This causes a Figure 1.

In this project it is used to enable control and interact with the application without the need to touch the object, through a natural user interface and using gesture and spoken commands may be. The Microsoft Kinect consists of an infrared projector, a color camera, an infrared sensor and Multi-array microphone that enables to: 1) Acoustic source localization 2) Ambient noise suppression Camera characteristics (1): The depth sensor captures video data in 3D under any ambient light conditions: 1) Infrared laser projector 2) Monochrome CMOS sensor Different depth measurement techniques are there. Here is a brief discussion about each of them: Lets first talk about the stereo triangulation method: (A stereo camera system can be used for determining the depth to points in the scene. Now first have to know what stereo camera is and what the features are. (A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate humanbinocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance)...

...RUNNING HEAD: Reflection on counseling 1 Reflection on counseling session recording Chua Ci Jie Introduction to Counselling James Cook University, Singapore Reflection on counseling Reflection on counseling Counseling is interpreted as a therapeutic practice of utilizing dialogue to assist clients in better understand and coping with their individual problems or health issues (Counseling, 2003). The individuality of the counselor has been extensively regarded as a vital tool in the provision of productive counselling sessions (Pieterse, Lee, Ritmeester & Collins, 2013) and has commonly introduced as “self as instrument” (Baldwin, 2000; McWilliams, 2004 as cited in Pieterse, Lee, Ritmeester & Collins, 2013). Therefore, the therapist’s application of self as instrument 2 affirm on the need for the counselor to have a satisfactory measure of self-awareness (Pieterse, Lee, Ritmeester & Collins, 2013). This essay attempts to enhance my individual self-awareness through reflecting on the counselling session, including the micro skills attempted as well as my strengths and weaknesses in conjunction with the micro skills. Biases and personal values are also identified. Counseling Session Opening I focused on trust building and goal setting in the opening section of counseling session to better facilitate the later session. Mutual trust between both the client and therapist is identified to be one of the significant elements to increase the effectiveness of the session...

...SCHOOL OF AUDIO ENGINEERING Diploma in Audio Engineering RA 101: INTRODUCTION TO STUDIO STUDIES RA 101.1: INTRODUCTION TO AUDIO RT 101.1 INTRODCUTION TO AUDIO Identifying the Characteristics of Sound Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color, so we are equipped with ears for the detection of sound. We seldom take the time to ponder the characteristics and behaviors of sound and the mechanisms by which sounds are produced, propagated, and detected. The basis for the understanding of sound, music and hearing is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium from one location to another. In this subject, we will investigate the nature, properties and behaviors of sound waves and apply basic wave principles towards an understanding of music. The Elements of Communication Communication: transfer of information from a source or stimulus through a medium to a reception point. The medium through which the information travels can be air, water, space or solid objects. Information that is carried through all natural media takes the form of waves - repeating patterns that oscillate back and forth. E.g. light, sound, electricity radio and TV waves. Stimulus: A medium must be stimulated in order for waves of information to be generated in it. A stimulus produces energy, which radiates outwards from the source in all directions. The sun...

...temperatures, the three phases of M3H(XO4)2 varies in the compound and have different crystal structures with its own unique degree of symmetry. At room temperature (about 298k), the compound will be at the phase 3 that consists of the features in a monoclinic structure and a space group of C2/m. As the temperature rises (to about 369k), the compound will then be at phase 2 and will produce a monoclinic-A2/a symmetry structure. When the temperature reaches 470k and above, the compound will be at phase 1. It will transit into a trigon structure and has a space group of R3-m. In the article mentioned, the M3H(XO4)2 contains different symmetrical forms when it has been exposed to different temperatures. Figure 2a is one example of the compound shown in phase 3.

Job-related Problems - can be generated in many ways from poor working conditions to dissatisfaction with the job itself. 2. Family-related Problems – can have a profound effect on employee job performance. Family crisis such as death, divorce, and major illnesses, as well as family pressures that conflict with job demands, are all situations in which employee productivity is likely to decrease 3. Other problems generated from outside the organization - other employees concerns such as legal, financial and social troubles outside the organization can cause problems of which managers need to be aware. ------------------------------------------------- Carrie Core Conditions for Effective Counseling 1. Empathy- 2. Respect – is often communicated by actions rather than words. Examples of such respect oriented behavior include being “for” the employee, willingness to work with the employee, regarding the employee as unique, suspending critical judgment, and expressing reasonable warmth. 3.
