Abstract: This paper focuses on the challenging task of counting the number of people in digital still images, which has important applications in many fields such as security, management, education, and commerce. This paper proposes a system that is based on the Viola-Jones face detection methods. This system consists of two parts: a) face detection and b) counting the detected faces. In the face detection part, the Viola-Jones (LBP and CART feature extraction) algorithm is applied to the input image. In the counting part, the detected faces are counted to estimate the number of people in the given image. The Viola-Jones algorithm is applied using 133 images from the People Image Groups dataset, and the best precision achieved is 96.9%. Overall, this paper presents a promising system for accurately counting the number of people in digital static images using a simple and costeffective approach

The genus Segestria Latreille, 1804 and the species Segestria florentina (Rossi, 1790) are recorded in Libya for the first time, based on a single adult female specimen

Abstract

Seven male specimens (one immature and six adults) of a rare species of Loureedia jerbae (El-Hennawy, 2005), are recorded for the first time in Libya, representing the first record of this species outside of Tunisia. Illustrations and a description are provided. Only the most recent adult of the specimens captured in October/November of 2019 to 2022 was examined, identified and described. Although Libya has one of the least recorded spider species in the Mediterranean region, it is promising to reveal more undiscovered and undocumented species through extensive research in this large country

In this paper, we introduced two novel subclasses of bi-univalent functions, Με (α, Β(α, ξ)) and ΗΣ (α, μ, Β(x, ξ)), utilizing Lucas-Balancing polynomials. Within these function classes, we established bounds for the Taylor-Maclaurin coefficients |a2| and a3, addressing the Fekete-Szegö functional problems specific to functions within these new subclasses. Moreover, we illustrated how our primary findings could lead to various new outcomes through parameter specialization.

Abstract

The research was conducted to discuss the impact of Derna floods on children’s education and their mental and psychological state, and emergency measures to confront the disaster. It has explained and talked about the tragedy that happened in Derna and other eastern cities. Furthermore, it has been mentioned the coping mechanism for schools. In addition, this research has been mentioned the impacts of storm Daniel on Derna. And, it has been discussed the effective steps to rebuild education facilities in the affected areas. Besides, it has been explained how to help children who have been affected by floods, which must have been awared by parents and caregivers. Finally, it has been explained the impact of trauma on children and some important tips for the sectors on how to be better support children and young people affected by flooding.
