Terahertz Time-Domain Spectroscopy (TDS) has emerged during the last two decades as a very popular technique for characterizing the low-energy excitations of several materials, gaseous, liquids and solids, as well as artificial materials as for instance epitaxial heterostructures and more. In recent years, the advances in THz technology allowed obtaining nonlinear optical effects with THz photons, showing remarkable results. In particular, THz Hyper-Raman Spectroscopy greatly expands the spectroscopic capability of the standard THz-TDS by combining intense and broadband THz pulses with a detailed analysis of the spectral content of the generated signal. It is evident that this improvement needs an adequate software support. The main parameter for coding the software which differs with respect to a standard THz-TDS software is the control of a motorized grating (monochromator), but several routines employed in the setup optimization stage rather than the actual measurement are needed as well. In this paper we present the TeraVision software, based on LabVIEW code, in order to highlight the solutions we adopted to tackle the main experimental challenges as well as to give a pleasant and user-friendly experience to expert users.

A user-friendly computer interface was created for the SPEX 1403 Raman spectrometer using the LabVIEW computer package. The interface allows the user to align the spectrometer easily, produce a graph of the Raman spectra, and save the file to a format readable by a spreadsheet program. The program has three screens: the first allows the user to set initial settings, the second allows the user to read from a particular wavelength for proper alignment, and the third allows the user to set scan settings and perform the scan. The interface was successful in reading Raman spectra easily and efficiently.

Fire detection systems are designed to discover fires and allow the safe evacuation of occupants as well as protecting the safety of emergency response personnel. This paper describes the design and development of a fire detection and alert system. Temperature and flame sensors are used to indicate the occurrence of fire. This work consists of two parts, which are transmitter and receiver, both using ZigBee wireless technology. Arduino Uno is used as the microcontroller at the transmitter part to control the sensor nodes and give alert when over temperature and flame are detected. At the transmitter, the collected data from the sensors are transmitted by an XBee module operated as router node. At the receiver side, an XBee coordinator module which is attached to a computer using USB to serial communication captured the data for further processing. In addition, an interactive and user-friendly Graphical User Interface (GUI) is developed. LabVIEW software is used to design the GUI which displays and analyze the possibility of fire happening. The system can display the fire location and provides early warning to allow occupants to escape the building safely.

Abstract Raman spectroscopy has undercome a major development during the last decades, making it more and more popular. One of the reason is that the instrumentation has become more accessible, by making the Raman microscopes much more affordable, reliable and user-friendly. Although the fundamental design has not really changed since the origins, it is important to know what the different components are made of and what is their purpose. Is that sense this chapter about the Optics of the Raman microscope will help to understand how the instrument works and what are the specifications and the useful characteristics.

Ageing is the major problem to the life span of high voltage insulation. Thus, continuous assessment method had gained an interest recently due to the economic concern. The measurement and evaluation of the dielectric response is one of the methods to diagnose transformer insulation condition. Dielectric diagnosis through polarization and depolarization current (PDC) measurement used dielectric response in time domain to assess the insulator. This paper presents the PDC data analysis system developed using LabVIEW software. The developed user-friendly system will enable user to run the recorded PDC data to evaluate the performance of the insulator in term of its conductivity and response function. The analysis result on PDC data recorded from field run using this system also been presented in this paper. Based on the obtained result, the system developed has been successfully helping user to do analysis on PDC data by giving the PDC pattern, conductivity value and response function of the insulator tested.

Purpose The paper aims to discuss design, fabrication, testing and simulation of a novel tactile probe used for measuring the stiffness of biological soft tissues/materials with a view to medical and surgical applications. Design/methodology/approach Both finite element modeling and experimental approach were used in this research. The novel tactile probe capable of recording force-deformation feedback is accompanied with the tactile-status-display which is a custom-designed user-friendly interface. This system can evaluate the stiffness in each part of force-deformation status. Findings The new system named novel tactile probe was fabricated, and the results on artificial materials (with different stiffnesses) and the sheep kidney (containing a hard object) were reported. Recording different stiffnesses, detecting hard object embedded in soft tissue and predicting the exact location of it are the main results that have been extracted through the diagrams obtained by the novel tactile probe system. Research limitations/implications The designed and fabricated system can be modified and miniaturized to be used during different minimally invasive surgeries in the future. Practical implications The most distinguishing feature of this novel tactile probe is its applicability during different laparoscopic surgeries, so the in vivo data can be obtained. Originality/value For the first time, a tactile probe has been designed and tested in the form of laparoscopic instrument which upgrades the efficiency of available laparoscopic instruments. Also, the novel tactile probe can be used in both in vivo and in vitro experimental setups for measuring the stiffness of sensed objects.
