Sunt doar niște miliardari interesați
de sănătatea planetei? Ori în spatele
filantropiei lor se ascund interese financiare
pe termen lung, care scapă, deocamdată,
puterii de înțelegere a unor cetățeni mai
preocupați de ce pun în strachină azi, decât
de ce se va întâmpla cu țara lor peste niște
ani? O întrebare legitimă, credem noi, în
cazul misterioasei fundații patronate de
Prințul Charles, despre care tocmai am aflat
că vrea să cumpere o halcă uriașă din
pădurile României. Prinț ai cărui conaționali
au creat proverbul de legendă
”nimeni nu îți dă un prânz gratuit”. Una
dintre știrile de top ale zilei de ieri e cea
preluată dintr-un ziar scoțian, potrivit căreia
fundația Carpathia, patronată de prințul
Charles, e interesată să cumpere nici mai
mult, nici mai puțin decât peste 100 de mii
de hectare de pădure din Carpați, pentru a
le transforma în rezervație naturală.

EXPERIMENTAL RESEARCHES OF CF MOTO 500- 5A/L7E
ATV’S DYNAMICS IN THE CASE OF TRAILER TOW
All-Terrain Vehicles are globally-spread nowadays both as entertaining
systems and as utility equipment. This paper presents a contribution to the
experimental research and graphical study of the data gained by developing a
practical protocol and methodology in order to monitor the kinematic and
dynamic parameters for three specific road surfaces, with all-terrain vehicle of
the type ATV CF MOTO 500-5A/L7e in the process of deceleration/acceleration
from different initial speed values. There were measured the braking distances
compared to the initial reference point and meanwhile were determined the
dynamic parameters of the ATV CF MOTO 500-5A/L7e during the
acceleration/deceleration process in the case of trailer towing, when a traction
force acts at the vehicle hook due to the 750 kg trailer. The opportunity of
researching this dynamic behavior is made possible by a research contract in
Technical University of Cluj-Napoca, showing that the trailer inertia force is
influencing both kinematics and dynamics during driving maneuvers of braking
and accelerating, as well as different conditions during usual ATV riding.

30-41 STRATEGII ALTERNATIVE DE TRANSPORT BAZATE PE TEHNOLOGII AVANSATE

ALTERNATIVE TRANSPORTATION STRATEGIES
BASED ON ADVANCED TECHNOLOGIES
Current systems of transport follow a transition period, regarding the
main sources of propulsive, but also about the movement principle. This
transition is imposed by the requirements of the population mobility acute
increasingly, travel times smaller, reducing the quantities of fossil fuels, the
need to reduce the level of pollution from transport, etc. Nowadays are currently
already used hybrid, hydrogen, electric cars and electromagnetic trains, but
they all require by the primary resource a kind of conventional energy, so the
desired effects are obtained at a reduced level. Thus, following the various
investigations, it was achieved the possibility of build some transport systems

30-29 LOCALIZAREA IRISULUI PENTRU SISTEMUL BIOMETRIC DE IDENTIFICARE A PERSOANELOR

LOCATION IRIS BIOMETRIC PERSON IDENTIFICATION
Methods of iris localization are investigated and new methods for pupil
and limbus boundary detection are introduced. Pupil boundary detection is
done by first pre-processed the iris image using exponential stretch and
Laplacian filter. Then the center and the radius are calculated using newly
developed algorithm. This algorithm does not require any threshold value to
determine the initial center since it is specified automatically. For limbus
boundary detection, the integro – differential operator is used. CASIA database
v1.0 is used to test the efficiency of the given algorithms. The accuracy of
localizing the iris correctly reaches 92 %. All the algorithms were implemented
using programming language Turbo C++.
Sunt investigate și introduse noi metode de localizare a irisului și de
detectare a marginii pupilei și a limitei limbusului (marginea corneei).
Detectarea marginii pupilei se face prin procesarea imaginii irisului, folosind
extinderea exponențială a filtrului Laplacian. Apoi centrul și raza sunt calculate
folosind un nou algoritm. Acest nou algoritm nu necesită nici o valoare limită,
pentru a determina centrul inițial al ochiului, din moment ce acesta este
specificat automat. Pentru detectarea limitei limbusului, se folosește operatorul
diferențial – linie integro, (baza de date CASIA), folosit pentru a testa eficiența
algoritmilor dați. Acuratețea localizării irisului ajunge până la 92 %. Toți
algoritmii au fost implementați folosind limbajul de programare TURBO C ++.

30-16 CONTACTE ELECTRICE PENTRU CURENŢI INTENŞI PRODUSE PRIN METALURGIA PULBERILOR

ELECTRICAL CONTACTS FOR STRONG CURRENTS
MADE BY POWDER METALLURGY
It was tested to be produced electrical contacts for strong currents by
infiltration after sintering, because the final density is much higher (11.100
kg/m3) and porosity is much lower (10.85 %). The infiltration after sintering
variant contains the steps: powder mixture preparation (W – 52 mass % – 520 g,
Ni – 2 mass % – 20 g, Cu – 46 mass % – 460 g, zinc stearate – 0,7 mass % – 7
g), homogenization, pressing (4.5 MPa), sintering (730 and 780 oC) and
infiltration (the green part is layed down on an electrocorindon EC 120 bed,
then the Cu green is on top of it, 1100 oC). In this variant the green part density
is almost constant (s = 0.062), with an identical porosity of the first after the end
of the process (14,28 %). By infiltration the density increased drastically (at
10,832 kg/m3), but its variations were increased also (s = 0.174) and porosity
decreased (at 10.85 %). The attained density is not sufficient for electrical
contacts work (11,100 kg/m3), but it is closer. The final composition of the
electrical contact was: W – 48.69 mass %, Ni – 1. 87 mass % and Cu – 49.44
mass %.
