The research aim is to measure the quality of hazy images using a no-reference scale based on the Transmission Component and Wavelet Transform (TCWT) by calculating the histogram in the High and Low (HL) component. The system is designed to capture several images at different levels of distortion from little to medium to high and the quality is studied in the transmission component. This measure is compared with the other no-reference measurements as a Haze Distribution Map based Haze Assessment (HDMHA) and Entropy by calculating the correlation coefficient between the no reference measurements and the reference scale Universal Quality Index (UQI). The results show that the proposed algorithm TCWT is a good measure of the quality of hazy images.

Strong Notion

Most of the existing privacy preserving clustering (PPC) algorithms do not consider the worst case privacy guarantees and are based on heuristic notions. In addition, these algorithms do not run efficiently in the case of high dimensionality of data. In this paper, to alleviate these challenges, we propose a new PPC algorithm, which is based on Daubechies-2 wavelet transform (D2WT) and preserves the differential privacy notion. Differential privacy is the strong notion of privacy, which provides the worst case privacy guarantees. On the other hand, most of the existing differential-based PPC algorithms generate data with poor utility. If we apply differential privacy properties over the original raw data, the resulting data will offer lower quality of clustering (QOC) during the clustering analysis. Therefore, we use D2WT for the preprocessing of the original data before adding noise to the data. By applying D2WT to the original data, the resulting data not only contains lower dimension compared to the original data, but also can provide differential privacy guarantee with high QOC due to less noise addition. The proposed algorithm has been implemented and experimented over some well-known datasets. We also compare the proposed algorithm with some recently introduced algorithms based on utility and privacy degrees.

Discourse Quality

In this paper, we apply a revised version of the Discourse Quality Index (DQI) developed by Steenbergen et al. to European Parliament (EP) debates. This updated measurement instrument, after the inclusion of new indicators, helps us identify not just the principles of European Union (EU) deliberation but most importantly the favourable contextual conditions of supranational deliberation. We illustrate the new DQI coding for selected debates over the last EU parliamentary term and discuss how the data can be employed to assess the overall quality of deliberation in the EP. At the same time we demonstrate that institutional issues matter for the quality of EP discourse, as do Members of the European Parliaments’ personal characteristics. Issue attributes on the other hand, influence supranational deliberation but not in the expected direction.

Inle Lake is the second largest inland lake in Myanmar. Floating gardens, mostly for tomato cultivation, are a unique and profitable method of agriculture used by people living on and around the lake. This study investigated the water quality of Inle Lake and how it has been affected by the different agricultural practices used in tomato cultivation on floating garden beds, by measuring pollution levels. Water samples were collected from the sites representing two types of agricultural practice from four villages. The first was designated as being grown under good agricultural practices (GAP), and the other as under non-good agricultural practices (non-GAP), with this study undertaken during wet season, 2019 and dry season, 2020. Two additional sets of water samples were collected as references. One of these sets was from the center of the lake and the other from an inlet stream to the lake. All water samples were analyzed for physical and chemical properties. The results found that Ca2+, Mg2+ and HCO3- were dominant in the lake surface water. The results showed significant differences in the mean values for some water quality parameters between the GAP and non-GAP of each study sites in both seasons. In particular, nutrient pollution from chemicals such as nitrogen and phosphorus from the non-GAP were significantly higher than those from GAP. Water quality index was calculated to describe the overall quality of lake surface water. It was observed that the water quality was almost threatened in the floating garden areas.  In comparison between two practices, the non-GAP gave the higher water quality index value than the GAP. This investigated that poor management of fertilizers usage has had a negative effect on the water quality of the lake. The differences seen in water quality from the GAP and non-GAP areas, point to ways to successfully manage sources of water pollution in order to better conserve the lake by sustainable agricultural production.

Abstract Water is a major source of economic development, social security and poverty reduction. The value of this resource on the one hand and its limitation on the other hand has led to increased management measures to maintain the quantity and quality of water by different communities. In this research, the water quality index (WQI) for the Dehroud and Tang Eram regions of Dashtestan in 2007 has been investigated. The average WQI in 2007 is 66,798. WQI was better off in the Northeast in 2007 than in the Southeast. The maximum values of PH, TDS and EC in 2007 are 7.9, 5000 and 7500, respectively.

This article describes a new image processing method in order to enhance the images under testing based on discrete Hermite wavelet filter. Discrete Hermite Wavelet Transform, which was used in image processing, including compression and noise removal was used after a number of theories proved to be mathematically ready for use in image processing. Through Discrete Hermite Wavelet Transform at different levels by finding a new filter and using it to find peak-to-noise ratio values (PSNR), compression ratio, mean square error (MSE) and bits per pixel found. Achieving a high compression ratio is acquired by using a new image decomposition algorithm. Bit reduction per pixel is obtained at the second level when increasing the level of decomposition to obtain compression ratio while PSNR is decreased with the basic wavelets, due to the features that characterize Discrete Hermite Wavelet Transform. A new filter was discovered more efficient and effective in reducing the error significantly in rebuilding, MSE and bits per pixel, the samples image is used show efficient intermittent wavelets that were built in this work. This method enabling to extract the integration matrices using Hermite wavelet operation matrix of integration that leads to improve the quality of images under testing. The obtained results for decreasing of and increasing of confirm the accuracy and effectiveness of the proposed method. These results can be used in many fields such as medicine, science treatment, compression, and noise removal images.

The article examines the quality of the course of the psychotherapeutic process at different levels of the client’s mental organization. It is shown that the experiences of a client with a low level of mental organization become incomprehensible to the psychotherapist, and the client becomes inaccessible. There is a tendency for the psychotherapist to avoid direct contact with the client's experiences, replacing emotional empathy with “knowledge” - “empathic knowledge”, “knowledgeable understanding”, and “sympathetic knowledge”. Such intellectual representation of the psychotherapist in contact can be useful both for the psychotherapist and for the client. At the same time, it results in the avoidance of direct emotional contact, which leads away from understanding the psychotherapeutic contact by C. Rogers. The denomination technique allows to clear the experience from the intellectual "husk" and get a pure living experience. This can happen in “body-experience-memory” space. The place the denominalization should be started depends on the characteristics of the organization of the client's psyche. Activation of one component of the specified space eventually leads to activation of the other. These components are the elements of the "emotional scheme." Three variants of denomination are described: 1) instructing - carrying a client into depth of experiences; 2) focusing - helping a client to enter the closed experiences; 3) support. The latter option is more specific for lower organized structures of the psyche. An important condition for the work of the psychotherapist against client’s protective function of intellectualization is actualization of the organismic tendency, otherwise the likelihood of retraumatization of the client is high.

As one of the key notions in postmodern theory, Otherness is defined as a quality of being different and separate from the Self. Within the postmodern theory, it is defined within the center-margin binary opposition discussed by theoreticians such as Linda Hutcheon. Yet, long before the theory, three of Nabokov’s novels depicted the concept of Otherness in their respective protagonists. Hermann in Despair, Humbert in Lolita and Kinbote in Pale Fire are assigned the role of the Other in their communities on different levels, all of which lead them to construct their own alternative realities where the margin is the center. This paper discusses the occurrence of the theoretical concept of the Other in the novels that predate the official theory of Otherness. The reoccurrence of the concept of the Other in literature, (especially in the period before the theoretical framework officially appeared) testify to the high relevance of the theory and the concept for discussing different phenomena of the human spirit and artistic experience.

The construction of syntactic tree structures is vital to different Natural Language Processing applications. In the meanwhile, the use of monolingual or bilingual structures directly affects the quality of Machine Translation systems. However, manually annotated syntactic tree structures are not only considered as a time consuming task but also a very expensive work, and automatic construction approaches cannot always guarantee the quality of the syntactic trees. In this paper, a system for annotating and constructing synchronous grammar tree structures in a semi-automatic way is proposed. The system is built in the Web environment with a graphical display for users to review and modify alignment relationships between nodes of the tree and strings or trees of the other language. The core part relies on the parsing of Constraint Synchronous Grammar, and consists of several modules in establishing alignments at different levels between the languages, including relationships between syntactic tree and strings of the other language, and bilingual tree alignments. Moreover, it provides import functions in obtaining monolingual skeletal bracketing syntactic tree and Translation Corresponding Tree structures for the creation of synchronous rules in order to have wider applicability.

Background: This is a summarizing discussion of the series. Six pieces of articles have been presented including two pilot studies and survey of the perception of healthcare professionals. The other four presented case observations from the different levels of health facilities.Methods: In this summary, a comparison between the four grades of facilities is presented with focus on completeness of patients’ contact details and clinical information regarding basic anthropometric data that can be easily collected anywhere.Results: It shows evidence that capacity and scope of diabetes services are in tandem i.e., least at the primary level and most at the tertiary facility. It also shows albeit anecdotal that the private general practices may be doing best in what they have capacity to do.Conclusions: The capacity for diabetes service in all tiers of the healthcare system. The need to advocate for diabetes register as a means to improve quality of service is highlighted.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).
