Local authentication in insecure environments
Information Processing Letters, 1987Abstract A local authentication mechanism in which system information such as user identifiers must be protected from both codebreaking and faking is proposed. The key is the two-step usage of public key cryptosystem which allows the public decryption.

Sensor Localization in an Obstructed Environment
2005Sensor localization can be divided into two categories: range-based approaches, and rang-free approaches. Although range-based approaches tend to be more accurate than range-free approaches, they are more sensitive to errors in distance measurement. Despite of the efforts on recovering sensors’ Euclidean coordinates from erroneous distance measurements,

Localization in Inconsistent WiFi Environments
2019As WiFi becomes more and more popular, indoor environments are often covered with access points (APs) many of which are temporarily generated by mobile devices. On the other hand, more and more infrastructural APs are equipped with beamforming capabilities which adjust radiation patterns according to client locations. These APs have large variations of

Frustation in local environment
Physica A: Statistical Mechanics and its Applications, 1984Abstract The sensitive and complicated dependence of frustation on local structure has been clearly demonstrated with an exact numerical solution. Its connection to realistic spin-glass is discussed.

ALF: An autonomous localization framework for self-localization in indoor environments
2011 International Conference on Distributed Computing in Sensor Systems and Workshops (DCOSS), 2011A lot of algorithms and applications can benefit from position information. GPS localization has become a standard for outdoor usage. But if a higher accuracy is needed or within GPS-denied areas providing this knowledge is still an open and nontrivial topic. Especially for unknown or dynamic environments.

Food conservation is one of the first examples of microbial environments manipulated by humans. Humans have applied “hurdles” to spoiling and pathogenic microbes such as salting-drying, acidification, fermentation, osmotic pressure, oxygen exclusion, heating, chilling, natural preservatives, alone and more recurrently in combinations for centuries ...

Using extensive and well-defined samples of nearby galaxies, we investigate the environment of the galaxies hosting low-luminosity AGNs. The AGNs hosted in luminous early-type spirals tend to reside in denser small-scale environments (

Angiogenic factors in bone local environment
Cytokine & Growth Factor Reviews, 2013Angiogenesis plays an important role in physiological bone growth and remodeling, as well as in pathological bone disorders such as fracture repair, osteonecrosis, and tumor metastasis to bone. Vascularization is required for bone remodeling along the endosteal surface of trabecular bone or Haversian canals within the cortical bone, as well as the ...

Vision-based Localization in RoboCup Environments
2001Knowing its position in an environment is an essential capability for any useful mobile robot. Monte-Carlo Localization (MCL) has become a popular framework for solving the self-localization problem in mobile robots. The known methods exploit sensor data obtained from laser range finders or sonar rings to estimate robot positions and are quite reliable
