Functional electrical stimulation (FES) has grown to be an effective and important element in the biomedical industry over the years. Due to this fact, it has become the basis of many researches. However, much work is focused on the theory and control technique with very few relating experiments. In this work, some key experiments were performed on the leg(More)
Many patients presenting hypertension before/after surgery should need to receive adequate medication. For example, patients with dissecting aneurysm often show extreme hypertension and an adequate control of blood pressure of the patient will lead to good surgical outcome. On the other hand, untreated hypertension after surgery may create complication.(More)
Learning a second language is challenging. Becoming fluent requires learning contextual information about how language should be used as well as word meanings and grammar. The majority of existing language learning applications provide only thin context around content. In this paper, we present Crystallize, a collaborative 3D game that provides rich context(More)

Wireless Sensor Networks (WSN) is widely used as an effective medium to integrate physical world and information world of Internet of Things (IOT). While keeping energy consumption at a minimal level, WSN requires reliable communication. Multicasting is a general operation performed by the Base Station, where data is to be transmitted to a set of(More)
Performing arts organizations aim to enrich their communities through the arts. To do this, they strive to match their performance offerings to the taste of those communities. Success relies on understanding audience preference and predicting their behavior. Similar to most e-commerce or digital entertainment firms, arts presenters need to recommend the(More)

Paper I: We study how annual plants with and without growth constraints should optimize their flowering time when productivity or season length changes. With a dynamic ontogenetic growth model and optimal control theory we prove that a bang-bang reproductive control is optimal under constrained growth and constant mortality rate. We find that growth(More)
MRI is often used in tumor localization for radiotherapy treatment planning, with gadolinium (Gd)-containing materials often introduced as a contrast agent. Motexafin gadolinium is a novel radiosensitizer currently being studied in clinical trials. The nanoparticle technologies can target tumors with high concentration of high-Z materials. This Monte Carlo(More)
14 kittens of 2-4 weeks were randomly divided into normal (N) and monocular deprivation (MD) groups. PVEP was tested before and after monocular deprivation by blepharorrhaphy for 12 weeks, when development of amblyopia was confirmed. Under TEM, the central retinal ganglion cells, the ipsilateral geniculate nucleus layers, the neurons of layer IV of visual(More)
14 kittens at 2-4 weeks of age were randomly divided into normal (N) and monocular deprived (MD) groups. Before the MD amblyopic models were made, pattern visual evoked potentials (PVEPs) were elicited from the experimental eyes. After the closure of 7 unilateral eyes (right 3, left 4) with operation, the two kitten groups were fed for 12 weeks under a same(More)
