Show moreHigh pressure processing (HPP) is readily gaining prominence worldwide as an alternative method of food preservation due to its benefits of improved quality, freshness and nutrient retention. The use of polymer-based flexible packaging materials has allowed application of HPP to prepackaged food products, without significant loss of physical and mechanical properties. However, there is limited data existing on migration properties in the materials before and/or after HPP. Therefore, it’s necessary to evaluate potential migration issues in pre-packed foods during HPP (Song and Koontz, 2012). This research was conducted to determine the migration properties in cast polypropylene (CPP) films during and after HPP (71°C and 700MPa) and a comparable thermal processing (TP, 71°C and 0.1MPa), using headspace (HS) gas chromatography (GC) coupled with mass spectrometer (MS) technique to quantify selected surrogate compounds (chloroform (CF), toluene (TOL), methyl salicylate (MS) and phenyl cyclohexane (PC)) in FDA-suggested food simulants (Miglyol and 10% Ethanol), and using dynamic mechanical analyser (DMA) to test glass transition temperature (Tg) of films. In general, HPP significantly decreased the migration of selected surrogates from CPP film into Miglyol or 10% Ethanol when compared to TP. For Miglyol, after 5min-HPP migration recoveries of CF, TOL, MS and PC were 53, 61, 24, and 16% respectively, while all compounds reached 100% after 5min-TP. For 10% Ethanol, recoveries of four compounds were 22.6, 12.6, 11.2, and 8.4% after HPP treatment, but were 51.0, 25.5, 21.2, and 9.2% with TP treatment. During storage at room temperature after processing, migration recoveries increased for both HPP/TP treated and non- xii processed samples; however, concentration of surrogated in HPP treated films were near or lower than those from non-processed and/or TP treated films. This research will help the U.S Food and Drug Administration (FDA) and the food industry to determine whether any safety issues related to chemical migration should be addressed concerning the use of HPP in production of prepackaged foods. The results may be used in the food contact notification and petition review processes of approving new packaging materials and components for use in HPP applications (Song and Koontz, 2011).

Show moreIn this thesis, deep belief net (DBN) is applied for detection of microcalcification (MC) clusters in digital mammograms. DBN is a relatively new type of neural network in machine learning which can learn complex structures from data by using a deep architecture. Based on a database of 200 clinical mammograms, a 3-level unsupervised network followed by a supervised back-propagation fine-tuning classifier is trained and tested. For each location in the image, the classifier is applied to decide whether there is an MC, and subsequently all the detected MCs are grouped into clusters. Free-response receiver operating characteristic (FROC) curves are used to evaluate the performance. The performance of DBN is compared to a well-known support vector machine (SVM) detector. Experimental results show that DBN can outperform SVM. In particular, DBN can achieve a detection rate of 83% at the cost of only one false positive cluster per image. These promising results show that DBN can be adopted in the study of object detection in medical image.

Show moreVehicular ad hoc networks (VANETs) enable vehicles to communicate with each other by equipping every vehicle with an on board unit (OBU). Many interesting and promising functionalities can be achieved in the VANETs, such as safety related application and data downloading application. In this thesis, we focus on the security and privacy provision as well as efficiency improvement of above two applications in the VANETs. In the safety related application, each vehicle periodically broadcasts messages including its current position, direction and velocity (which can be generated by a global positioning system (GPS) device) to inform its geographic data to its neighbors. Privacy is an important issue in VANETs. Meanwhile, some important security functionalities such as message authentication, integrity and non-repudiation should be integrated into the VANETs. In this thesis, we propose a distributed key management protocol based on group signature to provide security and privacy for vehicles. Distributed key management is expected to facilitate the revocation of malicious vehicles, verification efficiency, maintenance of the system and heterogeneous security policies, compared with the centralized key management assumed by the existing group signature schemes. In our framework, each road side unit (RSU) acts as the key distributor for the group, where a new issue incurred is that the semi-trust RSUs may be compromised. Therefore, we develop security protocols which are able to detect compromised RSUs and their malicious accomplices. Moreover, we address the issue of large computation overhead due to the group signature implementation. A practical cooperative message authentication protocol (CMAP) is thus proposed to alleviate the verification burden for vehicles. In the CMAP, on average, each vehicle just needs to verify a very small amount of received geographic messages. Compared with the existing probabilistic verification protocol, CMAP can save at least 40 % computation resource for vehicles. In the data downloading application, we propose a secure cooperative data downx loading framework for payment services in VANETs. In our framework, vehicles download data when they pass by an RSU and then share the data after they travel out of the RSU’s coverage. A fundamental issue of our framework is how vehicles share data with each other. Thus, we develop an application layer data sharing protocol (DSP) in which vehicles share their downloaded data one by one in sequence according to their positions. A better performance can be achieved by the proposed protocol because it is able to avoid medium access control (MAC) layer collisions and the hidden terminal effect. Analytical models are derived to quantitatively evaluate the impact of the distance between RSUs on the amount of data that vehicles can download in a drive through. The simulation results show that our protocol can download 87.4% more data for vehicles than the existing scheme “VC-MAC” when the distance between two consecutive RSUs reaches 10 kilometers. Moreover, we also address security and privacy issues in the process of data downloading and sharing. Both applicants’ exclusive access to the applied data and vehicles’ privacy are ensured by our framework. Compared with the communication overhead in the intuitive method, the communication overhead in our framework will be reduced to 50%. We also propose a security protocol to detect sybil attacks in privacy preserved VANETs. In the above two applications, vehicles’ location information is utilized to facilitate the efficiency. However, if malicious vehicles launch the sybil attack by forging several fake entities and claim they are at some certain positions. The overall performance of the applications will be compromised greatly. So, we propose a security protocol to detect sybil attacks by examining the rationality of vehicles’ positions. The attack detection utilizes the characteristics of communication. No extra hardware and little communication and computation overhead will be introduced to vehicles. Moreover, a smart attacker scenario in which a malicious vehicle may adjust its communication range to avoid detection and the malicious vehicles’ collusion scenario are also considered.

Show moreIn the illustrated embodiment a video cartridge contains an endless loop record tape with a multiplicity of channels, and a pair of pivotal guide arms for holding a length of tape in a taut condition to facilitate loading of the cartridge with the tape threaded between a capstan drive assembly and a transducer head. The downward movement of the cartridge into the operative position serves to retract the tape guides clear of the operating tape path. A tape tension arm is provided along the tape path in the cartridge and is so arranged as to apply tension to the tape as the cartridge is unloaded from the transducing machine. The tape reel in the cartridge is suspended on a bearing ball so as to provide very low resistance to rotation.

Show moreAziridinium ions are valuable and important intermediates to prepare complex nitrogen containing compounds. Various enantiomerically enriched -haloamines were synthesized as precursors to generate aziridinium ions in situ. Optically active aziridinium perchlorates or triflates were prepared and characterized using 1H and 13C NMR. Regioselective and enantioselective ring opening reactions of aziridinium ions with diverse nucleophilies including cyanide, azide, amines, hydride and water were extensively studied. An efficient one-pot synthetic route to enantiomerically enriched alcohols and amine precursors was developed. Development of the adequate bifunctional chelators is a critical step for radioimmunotherapy (RIT) of cancer. The practical and scalable regiospecific ring opening reactions of aziridinium ions with macrocyclic amines were utilized for synthesis of a series of bifunctional ligands including 3p-C-NETA, C-NE3TA, 3p-C-NE3TA, 3p-C-DECA, 3p-C-DE4TA, an optically active (S)-C-NE3TA, and bifunctional DTPA analogues for RIT using 90Y and 177Lu. Preparation of bifunctional chelators that can rapidly form 64Cu complexes with high stability is an imminent goal for effective PET imaging. A series of NOTA and NE3TA-based chelators were prepared. NE3TA-based bile acid conjugates and NE3TA- based dual receptor-targeted conjugates were synthesized and possess potential for application of targeted PET imaging with 64Cu.

Show moreThe idea of this project is to investigate the possibility of an underground airport with passenger facilities below and aircrafts above with minimum over-ground space. An important advantage is the possibility of loading and unloading passengers at two or more aircraft entrances thereby shortening the turn-around time of aircrafts. This accessibility can be more easily managed when approached from below. Furthermore, an underground facility is expected to provide several additional advantages: 1) greater freedom for aircrafts to get into position to efficiently load and unload; 2) potential for aircrafts to power-in and power-out of gate areas omitting the need for towing; 3) shorter walking distances for passengers due to greater compactness; 4) potential for an effective and efficient Automated People Mover (APM) system; 5) greater potential for systematic airport expansion when needed; 6) potentially reduced operating cost for ventilation, heating, and cooling. These advantages will answer many of the difficulties that current airports are experiencing today. However, in order to achieve these advantages, there are many important practical questions such as the spatial, environmental, structural aspects that need to be most carefully addressed. This project endeavored to investigate these important aspects as thoroughly as time and resources permit.

Show moreA new technique to reconstruct an object or environment in 3D using a single moving camera was developed. The technique requires only one camera moving through the environment. Once a set of images or a video is captured, a point cloud and the camera path of the environment or the object can be generated. The camera has to be calibrated in advance. The procedure of 3D reconstruction consists of the SIFT feature matching algorithm, the Epipolar geometry reconstruction, fundamental matrix algebra, points cloud triangulation, and the estimation of the camera motion. The algorithm explored in this thesis is only based on visual information captured by a single moving RGB-camera.

Show moreComputer models can describe complicated physical phenomena. Due to the highly nonlinear and complex nature, they require specially designed experimental inputs. One direction of computer experiment design is orthogonal Latin hypercube design which is widely used. This thesis reviews the most resent methods of orthogo- nal Latin hypercube designs, their constructing algorithms and important theoretical properties. These designs are easy to construct and preserve the orthogonal and equally-spaced projections. With large number of factors, orthogonal Latin hyper- cube designs enable researchers to estimate uncorrelated rst-order regression e ects, as well as higher-order e ects. For large number of runs, we reviewed general design method to construct large orthogonal Latin hypercubes from small orthogonal Latin hypercubes. A similar construction method for nearly orthogonal Latin hypercubes was discussed as well.
