SVANTE JANSON Abstract. Consider a sum ∑N 1 Yi of random variables conditioned on a given value of the sum ∑N 1 Xi of some other variables, where Xi and Yi are dependent but the pairs (Xi, Yi) form an i.i.d. sequence. We consider here the case when each Xi is discrete. We prove, for a triangular array ((Xni, Yni)) of such pairs satisfying certain conditions, both convergence of the distribution...

Steganography is the branch of information hiding for secret communication. The simplest and widely used steganography is the LSB based approach due to its visual quality with high embedding capacity. However, LSB based steganography techniques are not secure against statistical steganalysis mainly χ2 attack and Regular Singular (RS) attack. These two staganalysis can easily estimate the hidden...

PURPOSE To assess the shrinkage of Free Gingival Graft (FGG) in horizontal and vertical dimensions and calculate the changes in the surface area of the transplanted tissue in a 3 months period. MATERIALS AND METHODS total of 30 FGG were placed aiming to increase attached gingiva around recession sites. Vertical recessions, horizontal recessions, surface area, plaque index, gingival index, per...

Internet topology mapping studies utilize large scale topology maps to analyze various characteristics of the Internet. IP alias resolution, the task of mapping IP addresses to their corresponding routers, is an important task in building such topology maps. In this paper, we present a new probe-based IP alias resolution tool called palmtree. Palmtree can be used to complement the existing sche...

PURPOSE To compare conventional and endoscopic probing for congenital nasolacrimal duct obstruction in infants. METHODS Conventional probing was performed in 22 eyes of 18 patients, age range 7-14 months (mean 11.4 months). Probing was done with intranasal endoscopic visualization in 18 eyes of 14 patients, age range 7-13 months (mean 11.2 months). All were primary probing cases. RESULTS Af...

OBJECTIVE To determine the success of probing for congenital nasolacrimal duct obstruction in children aged under 10 years. DESIGN A retrospective study. MATERIAL AND METHOD The medical records of all children aged under 10 years diagnosed with congenital nasolacrimal duct obstruction between 1997 and 2007 who underwent probing and irrigation under general anesthesia were reviewed. Successf...

Background: Cigarette smoking is a significant risk factor for periodontal disease. It also causes pigmentation of oral mucosa. The present study was aimed to assess the effects of smoking on lip and gingival pigmentation and periodontal status and the relationship between pigmentation and periodontal parameters. Methods: A total of 109 smokers and an equal number of non-smoker controls (mean a...

purpose: to evaluate the nature of obstruction in difficult irrigation after probing for congenital nasolacrimal duct obstruction (cnldo). methods: in a prospective interventional study, the nature of obstruction in 75 eyes of 68 children aged between 12 and 23 months with cnldo who had difficult irrigation after probing was evaluated. all patients underwent monocanalicular silicone intubation....

PURPOSE The purpose of this study was to assess changes in periodontal probing depth (PD) over time for third molar and nonthird molar regions in young adults. PATIENTS AND METHODS The data were obtained from healthy subjects with 4 asymptomatic third molars, enrolled in an IRB-approved longitudinal trial. Demographic and oral health data were collected at baseline. Full-mouth PD, 6 sites per...

We present a methodological variation of cultural probing called playful probing. In playful probing games are developed according to the area investigated, to enhance participants’ involvement in the studies. The games are used as additional probing material and enhance participants’ involvement. Based on an experimental case study with 40 households participating in a ethnographic study on ne...
