Повний текст джерелаDestiny-2000 (Pvt.) Ltd. is a Multi-Level Marketing (MLM) company operating in Bangladesh which has adopted the Binary System of MLM. Binary systems are a multilevel marketing compensation plan which allows distributors to have only two front-line distributors. Everyone else goes beneath those people. The thing that determines whether one can get a commission from a person is not what level he is on, but rather how much purchase volume is generated in the levels between one and that person. Destiny-2000 has more than 130 Net offices (so called Net office which is bigger than Branch office) / Branch offices. As of 4th October 2007, the total number of distributors/ members is 1,322,361.
To make certain level of profit to keep the sales commission and incentive amount attractive for current and prospective distributors the minimum purchase volume for joining the sales network is moderately high by Bangladesh standard.
Destiny-2000 (Pvt.) Ltd. is exploring several options to attract their prospective and current members/ distributors. To this extend, the IPOS developed in this project reduces the one-time purchase burden for prospective members and allows current members to utilize their accumulated points by conveniently purchasing products from a shopping mall.
An Integrated Point of Sales (IPOS) System with Magnetic Stripe Card Reader application has developed based on shopping mall, which will be demonstrated using screen shots.
The complete system in this project, consist of several programs using Visual Studio.Net, C#, Visual Fox Pro, an SQL Database like MS SQL Server 2000, One GUI application, a set of reports using Crystal Report and magnetic stripe card reader, Point Privilege Card(PPC), Barcode Scanner etc.

A passive vibration isolator, which is simple and easy to manipulate, has some shortages such as incapability of dealing with large-amplitude, low-frequency vibration and physical limitations under specific structure. Hence, an active isolator is introduced to overcome the insufficiency of the passive isolators. Several types of active vibration isolators are available for industrial usage, for instance, hydraulic and electromagnetic ones. The objective of this thesis is to construct a magnetic actuation system which can be used to support a platform in which accurate positioning control and vibration isolation are required. To achieve the goal, three tasks are conducted sequentially: (1) hardware implementation, (2) dynamic model development and (3) performance tests. In the system configuration, the actuator drives a permanent magnet by generating magnetic force on it via two current-carrying coils. The exact magnetic force acting on the permanent magnet is obtained by practically measuring the magnetic field inside the actuator instead of applying the idealized formula. The dynamic model is also built up by analyzing the total force acting on the permanent magnet. The feedback control system is constructed by combing the actuator, an eddy current sensor, a PID controller and a PWM type power amplifier. Finally, a series of tests, which includes positioning control and vibration suppression, is conducted to examine the performance of the actuation system.

This is a research on classifying magnetic micro-particles in a micro flow tunnel, using an embedded inverted-laser tweezers system, a micro-flow pump and a micro-magnet. Manipulation of the particles in the micro-flow tunnel was achieved. An image recognition system integrated in the micro-flow tunnel was used to identify, count and separate different particles precisely using the laser and magnetic tweezers. In addition, the polystyrene particle classification experiment showed that the good separating result when the continuous flow and magnetic tweezers were used as manipulating forces. The higher the flow velocities were, the larger the separating rate would be, and thus, the largest separating rate was 80% in the study. When the continuous flow and laser tweezers were used as manipulating forces, the polystyrene particle separating rate could be 90%. When the laser tweezers and magnetic tweezers were used, it showed that laser tweezers was the most effective in trapping polystyrene particles when flow velocity were 0.08 to 0.25μm/s. The separating rate of the polystyrene particles could be as high as 95%, and the separating rate of the magnetic particles could also be as high as 85% when the flow rate is around 0.08 to 0.17μm/s.

Magnetic linear encoder has been increasingly integrated in various position control application while demands for high precision machine tool to produce high precision products increase. Due to its advantage in withstanding unclean environment such as oil, grease, and dust over an optical encoder, a magnetic encoder has become a desirable choice for machine tools. During the manufacture of magnetic encoding medium, the medium is not expected to be flat due to packaging induced plastic deformation and residual stress. Medium deformation will result in damaging the performance of the medium such as the accuracy and magnetic flux density distribution. In this paper, the research efforts are devoted to develop a roller leveling system to flatten the curved magnetic medium. Variable roller leveling system is designed and manufactured to perform parameter studies such as number of leveling and the indentation, diameter, and spacing of leveling rollers. Parameter studies are carried out to investigate how roller leveling can be integrated into the manufacture of magnetic encoding medium to improve mechanical deflection and residual stress. Optimal performance of the roller leveling system under specific parameter has been determined. Furthermore, experimental results demonstrate that roller leveling can significantly improve mechanical deflection of pre-stressed curve magnetic medium up to almost 60%. Residual deflection and residual stress of the deformed medium are validated through analytical studies using theory of Euler-Bernoulli beam and Elastica.

Influenza A virus (InfA) is one of the global public health threats that causes serious concern in human society every year. Currently, InfA is further classified into many subtypes based on 18 different hemagglutinin (HA) subtypes and 11 different neuraminidase (NA) subtypes. Because of the diversity of viral subtypes, it is difficult to prevent a novel influenza outbreak, especially for cross-species virus transmission. Early diagnosis and accurate subtyping of InfA can help clinical judgment and guide treatment of viral infections and effective flu outbreak management. Moreover, identification of viral subtypes can also offer a lot of valuable information such as origin, infectivity and antiviral resistance of the influenza virus. However, accurate diagnostic methods such as nucleic acid-based approaches are relatively time-consuming and labor-intensive. Furthermore, it requires expensive apparatus and well-trained personnel. Alternatively, rapid influenza diagnostic tests using immunoassays exhibit relatively low sensitivity and specificity and cannot differentiate subtypes of the InfA even though they can be performed in less than 30 minutes. Therefore, there is a crucial need for development of a highly sensitive, highly specific, rapid, easy-to-use and fully automated device for detection and subtyping of influenza viruses. Recently, polysaccharides, which were widely known as targets of viral HA, have been reported as probes to capture influenza viruses. In this work, a new array-type microfluidic chip was therefore developed and integrated into an automatic control system for multiple typing and subtyping of influenza viruses from virus-containing samples by using polysaccharide-coated magnetic beads and one-step reverse-transcription polymerase chain reaction (RT-PCR) processes targeting specific HA and NA. It is the first time that multiple viral subtyping (up to 12 InfA subtypes) could be automated starting from virus pretreatment to optical detection on an integrated microfluidic system. The entire virus detection process was shortened to less than 2 hours which was faster than conventional on-bench RT-PCR method and chip-based microarray systems. Under optimal operating conditions, the limits of detection of the specific primers were experimentally found to be from 2973 to 38 copy numbers for different influenza viruses via on-chip RT-PCR. The results showed significant improvement (around two orders of magnitude) when compared to our previous studies. The subtyping results also demonstrated that this integrated microfluidic system could identify 5 subtypes of InfA and 2 strains of influenza B viruses. In summary, the array-type microfluidic chip system provides a rapid, sensitive, and fully automated approach for the rapid detection and multiple subtyping of InfA.

Повний текст джерела15 usable patients with recurrent or newly diagnosed meningiomas using a 3T GE Signa scanner. Quantified spectral metabolite peaks were used to select voxels that had high or low alanine for tissue sampling. 3D 1H-MRSI was integrated into a standard image guided surgery (IGS) system; a mask of the voxel was loaded onto the IGS system allowing surgeons to precisely extract tissue intraoperatively according to biochemical mapping. Ex vivo NMR and conventional histological grading were performed on the extracted tissue. Results: Tumor spectra showed biochemically heterogeneous regions, especially for choline, lactate and alanine. Mean alanine concentrations were lower in more aggressive--histologically and immunohistochemically--regions of the meningiomas in the study. In addition, lower grade meningiomas showed high alanine at the tumor periphery with decreased central alanine. Ex vivo NMR was well-correlated with in vivo 3D 1H-MRSI. Conclusions: Non-invasive detection of various intratumoral biochemical markers using 3D 1H-MRSI can distinguish areas within meningiomas that express more aggressive features. There is regional heterogeneity in the concentrations of these markers within individual tumors. Furthermore, 3D 1H-MRSI may be able to exploit these regional differences to separate more aggressive from less aggressive areas within a given meningioma. Such knowledge may be useful to 5 the neurosurgeon faced with the task of meningioma resection, and in the planning adjuvant therapy for residual meningioma

Повний текст джерелаThis paper presents a novel on-chip antenna using standard CMOS-technology based on metasurface implemented on two-layers polyimide substrates with a thickness of 500 μm. The aluminium ground-plane with thickness of 3 μm is sandwiched between the two-layers. Concentric dielectric-rings are etched in the ground-plane under the radiation patches implemented on the top-layer. The radiation patches comprise concentric metal-rings that are arranged in a 3 × 3 matrix. The antennas are excited by coupling electromagnetic energy through the gaps of the concentric dielectric-rings in the ground-plane using a microstrip feedline created on the bottom polyimide-layer. The open-ended feedline is split in three-branches that are aligned under the radiation elements to couple the maximum energy. In this structure, the concentric metal-rings essentially act as series left-handed capacitances CL that extend the effective aperture area of the antenna without affecting its dimensions, and the concentric dielectric rings etched in the ground-plane act as shunt left-handed inductors LL, which suppress the surface-waves and reduce the substrates losses that leads to improved bandwidth and radiation properties. The overall structure behaves like a metasurface that is shown to exhibit a very large bandwidth of 0.350–0.385 THz with an average radiation gain and efficiency of 8.15dBi and 65.71%, respectively. It has dimensions of 6 × 6 × 1 mm3 that makes it suitable for on-chip implementation.

In this thesis, two kinds of metal oxide were proposed as martrix for flexible arrayed urea biosensor. The metal oxide films were Nickel Oxide (NiO) and Titanium dioxide (TiO2), respectively. The radio frequency sputtering system deposits the sensing film, and the screen printing technology were used to prepare the conductive arrayed wires and the reference electrode, and the epoxy is to encapsulate flexible arrayed urea biosensor. However, the covalent binding method is used to immobilize the enzyme between the matrix of the urea biosensor, and the preparation of the urea biosensors were completed. Afterwards, the sensing films of nickel oxide and titanium dioxide were modified by using graphene oxide and magnetic beads to improve its properties. The basically sensing properties of the two kinds of matrix biosensors were measured, and response time, interference and detection limit were also measured. However, the urea biosenosrs were integrated into the microfluidic measurement system and wireless real-time sensing system to measure the sensing properties of the urea biosensor under dynamic conditions, and it achieved remote monitoring. In addition, the feasibility of TiO2 matrix for the development of glucose sensors were discussed. Finally, we compared the literatures with the urea biosensors and glucose sensor in this thesis.

In this thesis, the screen-printed technology, radio frequency sputtering system and thermal evaporation system were used to integrate indium gallium zinc oxide (IGZO) membrane, Al electrode and silver paste onto the PET (polyethylene terephthalate) substrate. Next, the covalent bonding was used to immobilize ascorbate oxidase (AOX) onto the IGZO sensing membrane, and the flexible arrayed enzymatic L-ascorbic acid (L-AA) biosensor was completed. Besides, the graphene oxide (GO) and magnetic beads (MBs) were used to modify IGZO sensing membrane, and the electrochemical impedance spectroscopy (EIS) was used to confirm whether the GO and MBs were modified onto the sensing membrane successfully. According to the experimental results, the average sensitivity and linearity of MBs-AOX/GO/IGZO/Al L-AA biosensor were 78.9 mV/decade and 0.997, respectively. In this thesis, the response time, drift effect, hysteresis effect, anti-interfering effect and life time were investigated. Moreover, the sensing characteristic of L-AA biosensor which was integrated with microfluidic framework was detected under the different flow rates. Finally, in order to achieve remote monitoring, the L-AA biosensor was integrated with wireless real-time sensing system based on XBee module.

Знайти повний текст джерелаWith the Moore’s Law era coming to an end, much attention has been given to novel nanoelectronic devices as a key driving force behind technological innovation. Utilizing the inherent device physics of nanoelectronic components, for sensory and computational tasks have proven to be useful in reducing the area and energy requirements of the underlying hardware fabrics. In this work we demonstrate how the intrinsic noise present in nano magnetic devices can pave the pathway for energy efficient neuromorphic hardware. Furthermore, we illustrate how the unique magnetic properties of such devices can be leveraged for accurate estimation of environmental magnetic fields. We focus on spintronic technologies in particular, due to the low current and energy requirements in contrast to traditional CMOS technologies.
Image segmentation is a crucial pre-processing stage used in many object identification tasks that involves simplifying the representation of an image so it can be conveniently analyzed in the later stages of a problem. This is achieved through partitioning a complicated image into specific groups based on color, intensity or texture of the pixels of that image. Locally Excitatory Globally Inhibitory Oscillator Network or LEGION is one such segmentation algorithm, where synchronization and desynchronization between coupled oscillators are used for segmenting an image. In this work we present an energy efficient and scalable hardware implementation of LEGION using stochastic Magnetic Tunnel Junctions that leverage the fast parallel
nature
of the algorithm. We demonstrate that the proposed hardware is capable of segmenting
binary and gray-scale images with multiple objects more efficiently than
existing
hardware implementations.
It is understood that the underlying device physics
of spin devices can be used for emulating the functionality of a spiking
neuron. Stochastic spiking neural networks based on nanoelectronic spin devices
can be a possible pathway of achieving brain-like compact and energy-efficient
cognitive intelligence. Current computational models attempt to exploit the
intrinsic device stochasticity of nanoelectronic synaptic or neural components
to perform learning and inference. However, there has been limited analysis on
the scaling effect of stochastic spin devices and its impact on the operation
of such stochastic networks at the system level. Our work attempts to explore
the design space and analyze the performance of nanomagnet based stochastic neuromorphic
computing architectures, for magnets with different barrier heights. We illustrate
how the underlying network architecture must be modified to account for the
random telegraphic switching behavior displayed by magnets as they are scaled into
the superparamagnetic regime.
Next we investigate how the magnetic properties
of spin devices can be utilized for real world sensory applications. Magnetic
Tunnel Junctions can efficiently translate variations in external magnetic
fields into variations in electrical resistance. We couple this property of
Magnetic Tunnel Junctions with Amperes law to design a non-invasive sensor to
measure the current flowing through a wire. We demonstrate how undesirable
effects of thermal noise and process variations can be suppressed through novel
analog and digital signal conditioning techniques to obtain reliable and
accurate current measurements. Our results substantiate that the proposed
noninvasive current sensor surpass other state-of-the-art technologies in terms
of noise and accuracy.
