Research and Implementation on an Efficient Public Key Encryption Algorithm with Keyword Search Scheme
Venue: 2020 IEEE 5th International Conference on Cloud Computing and Big Data Analytics (ICCCBDA)
Year: 2020

With the rapid development of network storage service, a number of companies and individuals have stored data on a third party server. Encryption is an effective means of protecting the confidentiality and privacy of data, but retrieval on the encrypted data is a very difficult task. Thus, searchable encryption has become a hot topic in recent years. The paper first introduces the existing searchable encryption algorithms. Then studies the new PEKS scheme (NPEKS) and analyzes its performance and efficiency. In the end, based on NPEKS, introduced attribute encryption, designed a scheme which is suitable for corporate cloud storage environment. This scheme not only has the advantages of simplicity and efficiency, but also can realize the secret retrieval of the third party data. Experiments show that comparing with existing PEKS schemes and other improved schemes, this scheme has the advantages of simplicity and high efficiency. In addition, its security is the same as existing PEKS schemes.
Exploring Category Agnostic Clusters for Open Set Domain Adaptation
Venue: 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Year: 2020

Unsupervised domain adaptation has received significant attention in recent years. Most of existing works tackle the closed set scenario, assuming that the source and target domains share the exactly same categories. In practice, nevertheless, a target domain often contains samples of classes unseen in source domain (i.e. unknown class) The extension of domain adaptation from closed set to such open set situation is not trivial since the target samples in unknown class are not expected to align with the source. In this paper, we address this problem by augmenting the state of the art domain adaptation technique, Self Ensembling, with category agnostic clusters in target domain. Specifically, we present Self Ensembling with Category agnostic Clusters (SE CC) a novel architecture that steers domain adaptation with the additional guidance of category agnostic clusters that are specific to target domain. These clustering information provides domain specific visual cues, facilitating the generalization of Self Ensembling for both closed set and open set scenarios. Technically, clustering is firstly performed over all the unlabeled target samples to obtain the category agnostic clusters, which reveal the underlying data space structure peculiar to target domain. A clustering branch is capitalized on to ensure that the learnt representation preserves such underlying structure by matching the estimated assignment distribution over clusters to the inherent cluster distribution for each target sample. Furthermore, SE CC enhances the learnt representation with mutual information maximization. Extensive experiments are conducted on Office and VisDA datasets for both open set and closed set domain adaptation, and superior results are reported when comparing to the state of the art approaches.
Effects of free choice and outcome valence on the sense of agency: evidence from measures of intentional binding and feelings of control
Venue: Experimental Brain Research
Year: 2017

Everyday actions can be characterized by whether they are freely chosen or commanded by external stimuli, and whether they produce pleasant or unpleasant outcomes. To assess how these aspects of actions affect the sense of agency, we asked participants to perform freely selected or instructed key presses which could produce pleasant or unpleasant chords. We obtained estimates of the key press chord intervals and ratings of the feeling of control (FoC) over the outcomes. Interval estimates were used to assess intentional binding the perceived temporal attraction between actions and their outcomes. Results showed stronger binding and higher FoC ratings in the free compared to instructed condition. Additionally, FoC was stronger for pleasant compared to unpleasant outcomes, and for pleasant outcomes that were produced by freely selected compared to instructed actions. These results highlight the importance of free choice and outcome valence on the SoA. They also reveal how freedom of action selection and pleasantness of action outcomes can interact to affect the FoC.
Exact quantum search by parallel unitary discrimination schemes
Year: 2008

We study the unsorted database search problem with items $N$ from the viewpoint of unitary discrimination. Instead of considering the famous $O(\sqrt{N} Grover's the bounded error algorithm for the original problem, we seek for the results about the exact algorithms, i.e. the ones succeed with certainty. Under the standard oracle model \sum_j 1)\delta_{\tau j}|j> j| we demonstrate a tight lower bound {2/3}N+o(N) of the number of queries for any parallel scheme with unentangled input states. With the assistance of entanglement, we obtain a general lower bound {1/2}(N \sqrt{N} We provide concrete examples to illustrate our results. In particular, we show that the case of N=6 can be solved exactly with only two queries by using a bipartite entangled input state. Our results indicate that in the standard oracle model the complexity of exact quantum search with one unique solution can be strictly less than that of the calculation of OR function.
Analysis of Writing Styles of Research Article Introductions in EFL Academic Context: A Case of University of Dar Es Salaam Journal Authors
Year: 2020

The current study is a descriptive analytical account of how authors in EFL context adhere to or contravene Swales' (1990) moves structure in their writing of Introductions in academic writing. The specific academic genres under analysis were 115 research articles which were purposively chosen from five university of Dar es Salaam academic journals. The analysis adopted Swale's CARs (Create A Research Space) moves, namely; establishing a territory, establishing a niche and occupying a niche. Document review was the sole data gathering tool. Findings indicated that generally the majority of authors maintained fidelity to Swale's chronology of moves structure, notably in the fields of linguistics and engineering sciences. However, about a quarter of the authors started their Research Article Introductions (RAIs) with establishing a niche before claiming centrality and occupying a niche. It has been concluded that variations in academic disciplines are not a factor for authorial variations in their styles of moves structure.

Study of nanobubbles on hydrophilic and hydrophobic alumina surfaces
Year: 2016

Recent studies have shown that a high attractive force acts between poorly wettable surfaces, which cannot be explained by the conventional DLVO theory. This hydrophobic force is caused by very small bridging bubbles. Such forces can improve the efficiency in deep bed filtration applications using hydrophobized filter materials. An atomic force microscope was used for the characterization of nanobubbles by investigating hydrophilic and hydrophobic Al2O3 substrates in water at 10, 20 and 30 degC. The nanobubbles were therefore imaged via intermittent mode AFM. Height and diameter distributions were represented as well as calculated microscopic contact angles for bubbles of various sizes. The results were compared with force measurements and the potential differences were discussed. Furthermore, the stability of nanobubbles on smooth and rough alumina surfaces with an increasing scan force was presented.

Venue: 2020 IEEE Power Energy Society Innovative Smart Grid Technologies Conference (ISGT)
Year: 2020

The changing nature of the energy grid has prompted innovative solutions to incoming challenges. In a distribution system with microgrids, residents with distributed energy resources (DERs) and interactive devices can interact with one another and the grid to exchange energy. Blockchain based transactive energy could dynamically align active grid elements to incentivize demand side energy resource investment and energy efficient behavior. This work models a blockchain in the loop framework and simulates it using a Hyperledger Fabric blockchain network and the transactive energy simulation platform (TESP) Blockchain smart contracts are used to coordinate a microgrid market. Three market coordination schemes are compared, namely two auction less schemes and one simple auction scheme, in a 30 home microgrid with different DER penetration levels. Results show that the auction less scheme is more beneficial to community residents if the energy mix within the microgrid is diverse.

Roving Bandits? The Geographical Evolution of African Armed Conflicts
Year: 2015

The fighting in some civil wars primarily takes place in a few stable locations, while the fighting in others moves substantially. We posit that rebel groups that do not primarily fight for a specific ethnic group, that receive outside military assistance, or that have relatively weak fighting capacity tend to fight in inconsistent locations. We develop new measures of conflict zone movement to test our hypotheses, based on shifts in the conflict polygons derived from the new Georeferenced Event Dataset (GED) developed by the Uppsala Conflict Data Program (UCDP) Our empirical results provide support for the suggested mechanisms. We find that groups which lack strong ethnic ties and sufficient military strength to compete with government forces in conventional warfare fight in more varied locations. These findings improve our understandings of and expectations for variations in the humanitarian footprint of armed conflicts, the interdependencies between rebel groups and local populations, and the dilemmas faced by government counterinsurgency efforts.

The effects of social capital and human resources on financing and SMEs performance
Year: 2020

Small and medium enterprises (SMEs) still exhibit dominant contribution to the economy. SMEs manage to absorb greater labor force and to survive the economic crisis. Various efforts to empower SMEs have been less successful. Financing constraint, low quality of human resources, and limited marketing competence have been the typical problems of SMEs that harm SMEs' performance. Despite these problems, SMEs still manage to survive.  Using the sampling method of stratified random sampling with area strata, this study generates 203 small business units as the sample. The research was conducted by using accidental sampling. The quantitative and qualitative data are from primary and secondary sources. The data was collected by using observation, interview, and in depth interview. The variables in this research was analyzed by using path analysis.  Social capital positively affect SMEs' financing as indicated by the significance value of 0.000 a= 5% The stronger social capital of SMEs implied greater access of external financing sources. Social capital, and SMEs' financing positively affect SMEs' performance with 1% confidence level, and human resources positively affect SMEs' performance with 6% confidence level. The finding shown the stronger social capital and human resources increases SMEs performance.  The results show that social capital and SMEs' financing positively affect SMEs' performance, and human resources positively affect SMEs' performance. The results imply that stronger social capital and human resources increases SMEs performance. Social capital facilitates access to finance, marketing, production, and information. The results shows that human resources affect SMEs' performance. Social capital and human resources positively affect SMEs' financing. Similarly, social capital, human resources, and financing positively affect SMEs' performance.
Managing Student Behavior in an Elementary School Music Classroom: A Study of Class Wide Function Related Intervention Teams
Year: 2017

Classroom management is a common concern for teachers. Music teachers in particular experience unique behavior challenges because of large class sizes, uncommon pacing requirements, and performance based outcomes. Positive behavior support is an evidence based framework for preventing or eliminating challenging behaviors by teaching and reinforcing appropriate social skills. Class Wide Function Related Intervention Teams (CW FIT) a specific positive behavior support intervention involving social skills instruction, positive reinforcement, and group contingencies, has proven effective in elementary schools but has not been evaluated specifically in music classrooms. The present study sought to investigate the effectiveness of CW FIT in increasing on task behavior and teacher praise to reprimand ratios in a sixth grade music classroom. A single subject reversal (ABAB) design was used. Results indicated that student on task behavior increased when CW FIT was implemented. Teacher praise to reprimand ratios also improved. Results suggest the teacher and the students found CW FIT valuable and enjoyable. Study limitations and implications are addressed.
Relative Measurement Errors among Alternative Pension Asset and Liability Measures
Year: 2016

This study investigates the measures of pension assets and liabilities disclosed under SFAS 87 to determine which most closely reflect those that investors implicitly assess when they value the firm. Several measures considered to have conceptual merit are disclosed under SFAS 87, but no single method has been deemed most appropriate. The attributes of the three asset and five liability measurement alternatives disclosed and the controversies surrounding the FASB's deliberations on these alternatives are considered in the research design. Because the pension asset and liability issues in SFAS 87 relate to measurement and reflect a variety of unresolved questions, an approach directly comparing measurement error across alternatives is used. The research design utilizes relevance and reliability, two primary accounting choice characteristics advanced by the FASB. These two attributes are operationalized by the variances and levels of differences between alternative measures and the implied investors' assessment. In most prior studies using cross sectional valuation to address a variety of research questions, a model is posited and then tested by using book values as substitutes for unobservable variables. The measurement error is considered an econometric problem. Although the valuation equation assumed here is also based on unobservable market values, the measurement error is modeled, and the impact of the measurement error
Reliable Detection of Somatic Mutations in Fine Needle Aspirates of Pancreatic Cancer With Next generation Sequencing: Implications for Surgical Management.
Venue: Annals of surgery
Year: 2016

To determine the feasibility of genotyping pancreatic tumors via fine needle aspirates (FNAs) BACKGROUND FNA is a common method of diagnosis for pancreatic cancer, yet it has traditionally been considered inadequate for molecular studies due to the limited quantity of DNA derived from FNA specimens and tumor heterogeneity.  In vitro mixing studies were performed to deduce the minimum cellularity needed for genetic analysis. DNA from both simulated FNAs and clinical FNAs was sequenced. Mutational concordance was determined between simulated FNAs and that of the resected specimen.  Limiting dilution studies indicated that mutations present at allele frequencies as low as 0.12% are detectable. Comparison of simulated FNAs and matched tumor tissue exhibited a concordance frequency of 100% for all driver genes present. In FNAs obtained from 17 patients with unresectable disease, we identified at least 1 driver gene mutation in all patients including actionable somatic mutations in ATM and MTOR. The constellation of mutations identified in these patients was different than that reported for resectable pancreatic cancers, implying a biologic basis for presentation with locally advanced pancreatic cancer.  FNA sequencing is feasible and subsets of patients may harbor actionable mutations that could potentially impact therapy. Moreover, preoperative FNA sequencing has the potential to influence the timing of surgery relative to systemic therapy. FNA sequencing opens the door to clinical trials in which patients undergo neoadjuvant or a surgery first approach based on their tumor genetics with the goal of utilizing cancer genomics in the clinical management of pancreatic cancer.
