Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

ABSTRACT
Now-a-days, it became essential for
people work during nights and returning back to
homes late nights; also increasing crime rate
during night times. This can be best achieved by
implementing proper solar based lighting system
on Streets. The efficient monitoring and
controlling of this lighting system must be taken
into account. We will get more power
consumption, saving money through solar panel.
Also saving precious time, decrease the huge
human power through from the LDR, IR Sensors.
The Street lights are controlled through a
specially designed Graphical User Interface (GUI)
in the PC. The Zigbee technology can be used for
the street lights monitoring and controlling at the
PC end.
Keywords - Solar, control system, lighting system,
ZigBee, IR and LDR sensors.
I. INTRODUCTION
Lighting systems, particularly within the
public sector, are still designed per the previous
standards of reliability and that they don't usually
profit of latest technological developments. Recently,
however, the increasing pressure associated with the
raw material prices and also the increasing social
sensitivity to CO2 emissions are leading to develop
new techniques and technologies which permit
significant cost savings and larger respect for the
environment. In the literature we will notice three
solutions to those issues. The first one, and maybe the
most intuitive, is the use of recent technologies for
the sources of light. The LED technology is thought
as best solution but it offers several edges. I have
already thought of this risk, coming up with advanced
street lighting system based mostly on LEDs.
Researchers [1-4] have already thought of this risk,
coming up with advanced street lighting system
based mostly On LEDs.
The second resolution, and perhaps the most
revolutionary, is to use of remote management
system based mostly on intelligent lampposts that
send info to a central management system,
simplifying the management and maintenance.
Researchers [5],[8] have developed street lamp
system. Finally, the third solution is to use of
renewable energy Sources instead of typical power
sources, therefore taking care of the environment. In
this field, solar energy is the most often Used
resource. Our work aims at unification of the three
prospects, making an intelligent lamppost managed
by a controlled system that uses LED based
lightweight supply and is powered by Renewable
energy (solar panel and battery). The Control Unit is
to tackle the afore mentioned problems, an effective
way is to implemented through a network of sensors
to gather the relevant info associated with the Control
Unit and maintenance of the system, transferring the
data in wireless mode using the ZigBee protocol.
The ZigBee remote sensing and
management systems are widely described in the
literature; we can cite here as examples the
applications for the lighting systems. The ZigBee
remote sensing and management systems are widely
described in the literature; we can cite here as
examples the applications for the lighting systems [7-

II. GENERAL CONCEPT OF THE
SYTEM
In this project we are using Solar panel for
generating power and it will be stored into the
rechargeable battery from that we are giving power
supply to the street lights using relays.
In my project there are two modes of operations:
AUTO & MANUAL Operations.
AUTO: In this automatic mode operation we are
using LDR Sensor (Light Dependent Resistor) for
measuring light intensity for switched ON or OFF the
street light using relays. The main principle of LDR
is when the light intensity is low; light is going to be
ON otherwise it’s going to be OFF. For the efficient
reduction of power wastage IR (Infrared) Sensor is
integrated. If any vehicle or obstacle is detected using
IR sensor at that time it will check the light intensity

MANUAL: In this manual mode, the street lights are
controlled through a specially designed Graphical
User Interface (GUI) in the PC. The Zigbee
technology can be used for the street lights
monitoring and controlling at the PC end.
The system consists of a group of measuring
stations in the street. (One station located in each
lamppost) and a base station located nearby. The
system is designed as a modular system, easily
extendable. The LDR Sensors are used to observe
street conditions as the light intensity of daylight and,
depending on the conditions they activate or off the
lamps. Other factors influencing the activation are:
climatic conditions, seasons, geographical location,
and many possible alternative factors. For these
reasons every lamp is designed independent to decide
about the activation of light.

A.LDR SENSOR
A photo resistor or light dependent resistor
(LDR) is a resistor whose resistance decreases with
increasing incident light intensity; in other words, it
exhibits photoconductivity.
Photo resistors come in many types, it can be found
in many consumer items such as camera light meters,
street lights, clock radios, alarm devices, outdoor
clocks, solar street lamps and solar road studs, etc.It
is made by two cadmium sulphide (cds)
photoconductive cells with spectral responses Similar
to that of the human eye. The cell resistance falls
with increasing light intensity. Applications include
smoke detection, automatic lighting control, and
Batch counting and burglar alarm systems.
Temperature range for Storage is - 40°C to+85°C,
Operating range is -60°C to +75°C, Power supply is
18 to30VDC, For all sensors in the LDR series
Adjustable excitation is 4kHz to 33kHz Measuring
range from 10mm to 50mm.
B.IR SENSOR
Infrared Sensor is an electronic device, That
detects the infrared radiations to sense the aspects of
its surroundings, It detects motions that measures the
IR light from objects in the field of view, It’s
invisible to human eye because body temperature
radiates to infrared wavelength, It’s made by
pyroelectric materials (which generates exposed to
heat), IR light is longer than visible light wave length
but smaller than microwaves. Distance measuring
Range is 5- 300cm (Needed), Temperature is -10 to
60 Celsius, Power Supply is 5to5.5 V, power
Consumption current is 33mA.
The IR sensor receiver is a three terminal device used
to decrease the size of circuit, which consists of three
terminals, VCC, ground and output signal. When any
obstacle detected, the sensor receives the signal and
sends it to controller. The controller senses the
particular light on or off.
C.CONTROL UNIT
The Control unit controls all the lighting
system through a graphical user interface (GUI)
application window we can control all the lights and
we can monitor and status of the lights. The sensors
transfer the collected information to a PC.
Figure 3.Street lights Control and Monitoring using
GUI application.
The Control unit can be extended so that
other electrical Systems, not solely lampposts are
connected, and might send data regarding power
consumptions to a central system.

D.WIRELESS ZIGBEE NETWORK
ZigBee is wireless communication
technology primarily based on IEEE 802.15.4 norm
for communication among multiple devices in a
WPAN (Wireless Personal space Network).ZigBee is
intended to be less complicated than other WPANs
(such as Bluetooth) in terms of price and
consumption of energy. The ZigBee Personal space
Network consists of a minimum of one Coordinator,
one (or more) Devices and, if necessary, of one (or
more) Router. The bit rate of transmission depends
on the frequency band.
ZigBee transmission vary, depending on
the atmospheric conditions and therefore the
transmission power, ranges from tens to hundred
meters since the transmission power is deliberately
kept as low as necessary (in the order of few mW) to
keep up very low energy consumption. In proposed
system, the network is made to transfer data from the
lampposts to the central station. Data is transferred
purpose by purpose, from one lamppost to another
one where every lamppost has a distinctive address
within the system. The chosen transmission distance
between the lampposts assures that in case of failure
of one lamp within the chain, the signal will reach
other operational lamppost while not breaking the
chain.
ZigBee wireless communication network
has been implemented with the utilization of radio
frequency modules. They operate within the ISM
band at the frequency of 2.4 GHz. The receiver
sensitivity is high and therefore the chance of
receiving bad packets is low (about 1%). The
modules ought to be provided by 3V DC supply, and
then the power consumption is within the order of 50
mA. The module supports sleep mode where
consumption is smaller than 10μA.
III. REALIZATION OF THE SYSTEM
The operational test system operating in real
conditions is shown in Fig. 4. The proposed system
can be used for upgrade of existing typical lampposts,
as well. Power is provided by a battery, recharged
from a solar panel throughout the daytime. The
capacity of the battery depends on explicit parameters
of the application. In the designing part of a
photovoltaic system the irradiation curves of the
positioning has been studied to work out the
inclination and orientation of the surface of solar
panels that permit the optimal operation. For the
sizing of the panel it's necessary to calculate the
annual energy needed to power the lighting. The
charge controller manages the processes of the
battery charge and power provide. Current generated
by photovoltaic panels is handled by the controller to
produce an output current for battery charge. The
charging method should be conducted consistent with
the battery knowledge (capacity, voltage, chemistry,
etc.)
Figure 4. View of the test system.
IV. POWER MANAGEMENT AND
CONSUMPTION
The system was designed to operate stand-
alone, supplied by the energy from a solar panel. The
benefits from this type of power are important thus
avoiding the tedious and expensive wiring and
connection to external power network, enabling
considerable savings and ease of implementation.
The system is intended to be low-power, minimizing
the battery capacity and also the energy acquired
from the solar panel. These goals were achieved
through the utilization of the ZigBee module for
transmitting and receiving data, using LED lamps as
replacement of normal lamps and using special
power-saving solutions for microcontrollers and radio
modules.
The program that controls the system is
designed primarily to avoid wasting energy. Firstly,
as a result that the system works solely in the
darkness, avoiding waste of energy throughout
sunlight hours when the sole active device is the solar
panel that recharges battery. Secondly, the sensors
enable the system to operate solely when necessary.
Thirdly, the
System employs highly economical LEDs to ensure
correct illumination and assure energy savings.
Finally, when the system is disabled, all devices
(wireless module and microcontrollers) are in the
sleep mode, that permits negligible power
consumption. The wake-up is triggered by the change
of conditions (emergency device, presence sensor,
etc.). The selection of the battery depends on the
conditions where the system is installed.
V. ESTIMATION OF PRICES AND
SAVINGS
This proposed system may be criticized as
being expensive however we must consider its
advantages: slightly higher Prices of the lampposts
are compensated by lack of costly Wiring and the
availability of power network and considerably lower
prices of maintenance. Energy savings are of utmost

importance today. The goal is, therefore, the
reduction of operating prices of street lighting with
the creation of a system characterized by
straightforward installation and low power
consumption, powered by a renewable supply of
energy through solar panels with no harmful
atmosphere emissions and minimizing light pollution.
Making a short comparison with the normal street
lighting systems: Supposing that one lamp is
switched on for 4,000 hours per year. One streetlight
has a median consumption of 200 W and the price of
energy is of 200€ yearly. If suppose a 5 km long
street, it is necessary to install 125 street lights (one
each forty meters), with yearly energy consumption
of 25.000€. With the system presented in this paper,
every lamp uses about 20-25 W (95% of energy
consumed by the LEDs).With an equivalent example
as before, energy cost decrease to 5.000€ (savings of
80%).Based on the field tests another possibility of
energy Savings becomes evident. Classical system
consumes energy independently if it is needed or not.
It is active for about 10 hours daily and the total
number of working hours is about 300 per month,
versus 87-108 hours proposed system, savings of
about 66% to 71% are expected.
Finally, since the system is powered by
solar panels (with batteries), the energy price does
not depend on provider costs. Consequently, the sole
price to consider is that of the installation and
implementation of the system; with following
Savings thanks to lower maintenance and energy
savings.
VI. CONCLUSION
In this paper a proposal of an intelligent
wireless street light control and monitoring system is
described that integrates new technologies, offering
ease of maintenance and energy savings. This is
obtained by using the highly economical lamp post
technology supplied by renewable energy provided
by the solar panels and by using the intelligent
control unit of the lampposts. By using LDR and IR
sensors we can save some more power and energy,
and also we can monitored and controlled the street
lights using GUI application, we can get the status of
the lights in street or highway lighting systems. The
proposed system is especially appropriate for street
lighting in urban and rural areas where the traffic is
low at times. The system is versatile, extendable and
totally adjustable to user needs.
