An Instance of Somatoform Disorder  [PDF]
Armando Simon
Open Journal of Medical Psychology (OJMP) , 2013, DOI: 10.4236/ojmp.2013.21004
Abstract: A case study is presented of a prison inmate with Somatoform Disorder, a relatively rare type of mental illness. In this particular case symptomatology revolved around his claim that some of his teeth were rotten, resulting in great pain, in spite of several diagnoses by dentists. When said teeth were extracted, inmate would express satisfaction, whereupon several weeks later the same complaint would resurface and the cycle began anew. Of the various types of mental illnesses listed in the DSM, there are some that are infrequently seen [1,2] One of these is Somatoform Disorder, a category of mental illness for which there is a paucity of research, partly due to diagnostic difficulties and controversies [3,4] and we would like to present a case study of just such an instance.
Model for a UV Laser Based Local Polymer Surface Halogenation Process Using a Gaseous Precursor  [PDF]
Simon Kibben
Modeling and Numerical Simulation of Material Science (MNSMS) , 2014, DOI: 10.4236/mnsms.2014.41003
Abstract: An analytical model describing the physical relations of a UV-based process for halogenation of polymeric surfaces is presented. The process allows, depending on the parameters, a local halogenation with sharp edges at the interfaces to areas where no halogenation is desired. This is achieved via a nonreactive halogen-containing gaseous precursor and a UV source providing photons which dissociate the precursor photolytically. Thus, only where the UV photons affect the precursor, halogens are generated and the polymer is being halogenated.
Internet of Things: Services and Applications Categorization  [PDF]
Matthew Gigli, Simon Koo
Advances in Internet of Things (AIT) , 2011, DOI: 10.4236/ait.2011.12004
Abstract: In this paper we attempt to categorize the services provided by the Internet of Things (IoT) in order to help application developers build upon a base service. First we introduce the four main categories of services, and then follow by providing a number of examples of each of the service categories so as to provide an example of how each type of service might be implemented, and how it can be used to build an IoT application.
Distributed Air & Missile Defense with Spatial Grasp Technology  [PDF]
Peter Simon Sapaty
Intelligent Control and Automation (ICA) , 2012, DOI: 10.4236/ica.2012.32014
Abstract: A high-level technology is revealed that can effectively convert any distributed system into a globally programmable machine capable of operating without central resources and self-recovering from indiscriminate damages. Integral mission scenarios in Distributed Scenario Language (DSL) can be injected from any point, runtime covering & grasping the whole system or its parts, setting operational infrastructures, and orienting local and global behavior in the way needed. Many operational scenarios can be simultaneously injected into this spatial machine from different points, cooperating or competing over the shared distributed knowledge as overlapping fields of solutions. Distributed DSL interpreter organization and benefits of using this technology for integrated air and missile defense are discussed along with programming examples in this and other fields.
Market Expansion Effects with Differentiated Goods: Monopoly versus Atomistic Competition  [PDF]
Paul Madden, Simon Rudkin
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.23055
Abstract: In a horizontally differentiated goods market, where consumers face heterogeneous costs of entering the market and exhibit a taste for variety (via CES preferences) over the continuum of substitute goods, lowering the general market price level leads to increased consumer entry—the market expansion effect. Since atomistic competitors (each supplying 1 good) cannot influence this general price level, whilst a (multi-product) monopolist can, monopoly may lead to lower prices. In a model where market expansion effects are potentially large, the paper shows how monopoly leads to socially desirable lower prices, and greater variety, even when goods are arbitrarily close substitutes.
An Algorithm for Classification of Algal Blooms Using MODIS-Aqua Data in Oceanic Waters around India  [PDF]
Arthi Simon, Palanisamy Shanmugam
Advances in Remote Sensing (ARS) , 2012, DOI: 10.4236/ars.2012.12004
Abstract: Increasing incidences and severity of algal blooms are of major concern in coastal waters around India. In this work an automatic algorithm has been developed and applied to a series of MODIS-Aqua ocean color data to classify and monitor four major algal blooms in these waters (i.e., Trichodesmium erythareum, Noctiluca scintillans/miliaris (green/brown), and Cochlodinium polykrikoides (red)). The algorithm is based on unique spectral signatures of these blooms previously reported by various field sampling programs. An examination of the algorithm results revealed that classified blooms agree very well with in-situ data in most oceanic waters around India. Accuracy assessment based on overall, user’s and producer’s accuracy and Kappa accuracy further revealed that the producer’s/user’s accuracy of the four algal blooms were 100% / 100%, 79.16% / 79.16%, 100% / 80%, 100% / 86.95%, respectively. The Kappa coefficient was 1.01. These results suggest that the new algorithm has the potential to classify and monitor these major algal blooms and such information is highly desired by fishermen, fish farmers and public health officials in this region. It should be noted that coefficients with the new algorithm may be finetuned based on more in-situ data sets and the optical properties of these algal blooms in oceanic waters around India.
Global Electronic Dominance with Spatial Grasp  [PDF]
Peter Simon Sapaty
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2012, DOI: 10.4236/ijcns.2012.511076
Abstract: A high-level control technology will be revealed that can dynamically establish overwhelming dominance over distributed networked systems with embedded electronic devices and any communications between them. It is based on implanting of universal control modules (that may be concealed) into key system points which collectively interpret complex but compact mission scenarios in a special high-level Distributed Scenario language (DSL). Self-evolving and self-spreading in networks, matching them in a super-virus mode, DSL scenarios can analyze their structures and states and set up any behavior needed, including creation of benign or elimination of unwanted infrastructures. The scalable technology allows us to convert any distributed networked systems into a sort of integral spatial brain capable of analyzing and withstanding unpredictable situations in a variety of important domains.
A case of an ectopic cervical thymic cyst  [PDF]
Simon Davey, Janet McNally
Case Reports in Clinical Medicine (CRCM) , 2013, DOI: 10.4236/crcm.2013.22041

Ectopic cervical thymic cysts are uncommon lesions and definitive preoperative diagnosis is not always possible. Surgical excision is recommended due to the small but possible chance of malignant degeneration in adulthood. We present a case of a nine year old boy with an asymptomatic lesion in his neck, discuss the differential diagnoses of such lesions and treatment considerations.

Lossless Compression of SKA Data Sets  [PDF]
Karthik Rajeswaran, Simon Winberg
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.54046

With the size of astronomical data archives continuing to increase at an enormous rate, the providers and end users of astronomical data sets will benefit from effective data compression techniques. This paper explores different lossless data compression techniques and aims to find an optimal compression algorithm to compress astronomical data obtained by the Square Kilometre Array (SKA), which are new and unique in the field of radio astronomy. It was required that the compressed data sets should be lossless and that they should be compressed while the data are being read. The project was carried out in conjunction with the SKA South Africa office. Data compression reduces the time taken and the bandwidth used when transferring files, and it can also reduce the costs involved with data storage. The SKA uses the Hierarchical Data Format (HDF5) to store the data collected from the radio telescopes, with the data used in this study ranging from 29 MB to 9 GB in size. The compression techniques investigated in this study include SZIP, GZIP, the LZF filter, LZ4 and the Fully Adaptive Prediction Error Coder (FAPEC). The algorithms and methods used to perform the compression tests are discussed and the results from the three phases of testing are presented, followed by a brief discussion on those results.

Jingjing Xia, Simon Liao
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B038

In this research, we have performed pulse analysis on the data of 127 subjects collected from Department of Cardiology at Shandong Provincial Hospital in China. By taking the first and third derivatives of an entire pulse wave, we have firstly identified the locations of wave foot, systolic peak, and reflected point. Then we calculated Reverse Shoulder Index (RSI) and Ratio of Distance of the evaluated subjects, and correlated them to age, the history of hypertension, and different cardiovascular diseases of the subjects.
